If radus of earth shrinks by 0.1% without change in its mass, the percentage change in the duration of one day

If the radius of earth shrinks by 0.2% without change in its mass, the % change in its angular velocity is

If the radius of the earth shrinks by 0.2% without any change in its mass, the escape velocity from the surface of the earth

If radius of the earth is doubled without change in its mass, what will be the length of the day?

If the radius of the earth decreases by 1% without changing its mass, will the acceleration dure to gravity at the surface of the earth increase or decrease? If so, by what per cent?

When the radius of earth is reduced by 1% without changing the mass, then the acceleration due to gravity will

If the earth were to suddenly contract to 1//n^(th) of its present radius without any change in its mass, the duration of the new day will be nearly

If the mass of the earth is kept constant and its radius is made half, then the duration of the day will be where T is the present duration of the day.
