Question

Neglect the effect of rotation of Earth. Suppose the Earth suddenly stops attracting objects placed near its surface .A person standing on the surface of the earth will
(A) Fly up
(B) Slip along the surface
(C) Fly along a tangent to the earth’s surface
(D) Remain standing

Answer 1

It is instructed in the question to Neglect the effect Earth’s rotation. If we Neglect the effect of Earth's rotation there will be no movement of the earth with this condition. We have to find what happens if the earth stops attracting the objects on its surface. Lean about the concept of gravitation to get the correct answer.

Complete step by step solution:
Rotation of the planet earth is the rotation of Earth around its own axis. Earth completes its one rotation in twenty four hours, exactly twenty three hours, fifty six minutes, and four seconds.
The earth attracts the objects on the earth with a force, the force which attracts is known as gravitational force and when the earth attracts the object on the surface of the earth its mass is known as weight of the object.
If we neglect the rotation of the earth there will be no movement by the earth so even if the earth stops attracting objects on its surface there will be no change in the position of the object. The object might not undergo any further movements and it stays still.
So if a person is standing on the surface of the earth, he will remain standing in the same place if the earth stops attracting objects if we neglect the rotation of the earth.
Hence the correct answer is option D) Remain standing.

Note:
The gravitational force is defined as the force which attracts any two objects with mass. The gravitational force is only attractive; it cannot be repulsive as it always tries to pull objects with masses together, it never pushes the masses apart. The interesting fact is that every object in the universe including us, is pulled by every other object in the universe. This is known as the Newton's Universal Law of Gravitation.
