If the earth suddenly shrinks

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?

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. This is a golden opportunity for those candidates who want to get into the teaching profession in the state of Uttar Pradesh. For the upcoming cycle, a total of vacancies are expected.

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. Statement-2 : When the size of the earth will change, its moment of inertia will also change. If earth shrink without change in mass to half it's present size. Length of the day would become 6 hours. As size of earth changes its moment of inertia changes.

Concept : Acceleration due to gravity : The acceleration achieved by any object due to the gravitational force of attraction by the earth is called acceleration due to gravity by the earth. Learn today! If density of earth increased 4 times and its radius become half of wh

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 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:. Therefore, the gravitational acceleration at the Earth's surface will become four times its current value if the Earth suddenly shrinks to half its current radius while maintaining a constant mass.

The diameters of two planets are in the ratio and their mean densi What is not correct about ultrasonic waves? Ace your Gravitation preparations for Acceleration due to gravity below and above the surface of earth with us and master Physics for your exams. Is moment of inertia of a body a constant quantity? If the earth shrinks without change in mass, what will be the effect on the value of acceleration due to gravity g? If the radius of earth suddenly shrinks to half without change in the mass. A diverging lens is also known as. In uniform circular motion the following quantities remain constant-. Find the ratio of the radii of gyration of a circular disc and a circu As size of earth changes its moment of inertia changes. At what depth below the surface of the earth acceleration due to gravi If the earth suddenly shrinks without changing mass to half of its p View Solution. The duration of the day T will decrease.

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.

Write SI unit of angular momentum:. If the earth suddenly shrinks without changing mass to half of its p If the earth shrinks without change in mass, what will be the effect on the value of acceleration due to gravity g? A simple pendulum has a time period T 1 when on the earth's surface a When a body is taken from the equator to the poles, its weight A nollow sphere and a solid sphere having same mass and same radii are Radius of the earth is R. 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. Statement-2 : When the size of the earth will change, its moment of inertia will also change. What is not correct about ultrasonic waves? In the light of the above statements, choose the correct answer from the options given below:.
