1.	If the earth stops rotating the value of ‘g’ at the equator will:A. increaseB. remains sameC. decreaseD. none of these
Answer» If the earth stops rotating, then the value of g at the equator increases and becomes equal to the value at poles. This is because, if the earth will stop rotating, then the equatorial bulge will vanish and earth will have a uniform radius and since, g ∝\(\frac{1}{r^2}\) so g is same through the surface of earth now. Hence, option A is correct.

If the earth stops rotating, then the value of g at the equator increases and becomes equal to the value at poles. This is because, if the earth will stop rotating, then the equatorial bulge will vanish and earth will have a uniform radius and since, g ∝\(\frac{1}{r^2}\) so g is same through the surface of earth now.

Hence, option A is correct.

A star 2.5 times the mass of the sun and collapsed to a size of 42 km rotates with a speed of 1.2 rev. per second. (Extremely compact stars of this kind are known as neutron stars. Certain stellar objects called pulsars belong to this category). Will an object placed on its equator remain stuck to its surface due to gravity? (mass of the sun = 2 × 1030 kg).
