If the earth suddenly shrinks

Acceleration due to gravity of the earth having mass M and radius R on earth surface is given by:. Last updated on Mar 31, In this year's recruitment cycle, a total of vacancies were released.

If the radius of the earth contracts to half of its present value without change in its mass, what will be the new duration of the day? If earth shrinks then the duration of day. The sun rotates about its axis once in 27 days. If it suddenly shrinks to one-eighth of its original volume, mass remaining same, then what will be its new period of rotation? The height of geostationary orbit above the surface of the earth is h. Radius of the earth is R. The earth shrinks to half its present radius mass remaining unchanged.

If the earth suddenly shrinks

If the earth suddenly shrinks without changing mass to half of its present radius, the acceleration due to gravity will be. If the earth suddenly shrinks without changing and half of its present radius , the acceleration due to gravity be. If the earth shrinks without change in mass, what will be the effect on the value of acceleration due to gravity g? Statement I: If the earth suddenly stops rotating about its axis, then the acceleration due to gravity will become the same at all the places. Statement II: The value of acceleration due to gravity is independent of rotation of the earth. Suppose the earth shrinks such that its radius decreases to half the present value. What will be the acceleration due to gravity on the surface of the earth? A satellite is revolving around earth in its equatorial plane with a period T. If the radius of earth suddenly shrinks to half without change in the mass. Then, the new period of revolution will be. Statement-1 : If earth shrink without change in mass to half of its present size, length of the day would become 6 hours.

If the earth suddenly shrinks without changing mass to half of its present radius, the acceleration due to gravity will be. Statement-2 : When the size of the earth will change, if the earth suddenly shrinks, its moment of inertia will also change. Given below are two statements: one is labeled as Assertion A and the other is labeled as Reason R.

What would happen if our Sun—as it actually exists, in the present—suddenly decreased in mass, plummeting from 1 solar to mass to a mere. In order to understand what impact this would have on our solar system and on Earth, especially , you need to have a basic understanding of how mass is related to gravity. Essentially, an increase in mass means an increase in gravity, while a decrease in mass means a decrease in gravity. So if the Sun spontaneously lost half its mass gasp, shudder, the horror! With that said, we all hopefully know that life on Earth is dependent on the light and heat that it receives from the Sun. If the Sun's mass abruptly halved, it would certainly have a huge impact on these key points; it would grow cooler and redder and eventually transform into a red dwarf.

If the earth suddenly shrinks

If the Earth suddenly shrinks without changing its mass to half its current radius,then the new gravitational acceleration at earths surface will be. If the Earth were to suddenly shrink to half its current radius while keeping its mass constant, the gravitational acceleration g at the Earth's surface would be four times its current value. If the Earth's radius becomes half its current value, the new radius R' will be:.

If the earth shrinks without change in mass, what will be the effect on the value of acceleration due to gravity g? Text Solution. An object is falling freely from a height x. The depth d, at which the value of acceleration due to gravity becomes Suggested Test Series. Weight of a body is maximum at For the upcoming cycle, a total of vacancies are expected. What will be the acceleration due to gravity on the surface of the earth? One electron volt is equal to :. If earth shrinks then the duration of day. A simple pendulum has a time period T 1 when on the earth's surface a Testbook Edu Solutions Pvt. A nollow sphere and a solid sphere having same mass and same radii are The earth shrinks to half its present radius mass remaining unchanged.

Like any good gift giver, Earth is constantly giving and receiving materials with the surrounding solar system. For instance, dust speeding through space regularly bombards our planet in the form of shooting stars, and gases from Earth's atmosphere regularly seep out into space. So, if Earth is continuously giving away matter, as well as acquiring new material, is it expanding or shrinking?

The following is the relation between the object distance and the image distance in a plane mirror image :. If the earth suddenly shrinks without changing mass to half of its p View Solution. Assertion A : When an artificial satellite moves around the earth in a circular orbit with a constant speed, its velocity is not constant because the direction of motion of the satellite is changing continuously. If the Earth suddenly shrinks so as reduce its volume, mass remaining unchanged, what will be the effect on the duration of the day? Statement-1 : If earth shrink without change in mass to half of its present size, length of the day would become 6 hours. Write SI unit of angular momentum:. As size of earth changes its moment of inertia changes. If the radius of the earth contracts to half of its present value without change in its mass, what will be the new duration of the day? About what axis would a uniform cube have its minimum moment of inerti If density of earth increased 4 times and its radius become half of wh If the earth shrinks without change in mass, what will be the effect on the value of acceleration due to gravity g? If earth shrink without change in mass to half it's present size. Length of the day would become 6 hours. According to Kepler's first law, the planets move around the Sun:.
