(A) There are points outside the earth where the value of g is equal to its value at the equator.
(B) There are points outside the earth where the value of g is equal to its value at the poles.

विकल्प

  • Both A and B are correct.

  • A is correct but B is wrong.

  • B is correct but A is wrong.

  • Both A and B are wrong.

उत्तर

A is correct but B is wrong.

We know that the value of acceleration due to gravity decreases when we go up from the surface of the Earth. If we take the into account the effect of bulging of the Earth due to its rotation, we can say that acceleration due to gravity is maximum at the poles and minimum at the equator

So, there are points above both the poles where the value of g is equal to its value at the equator.
