Find the change in length of a day if the radius of earth changes by `1/2`% considering the mass constant. Assume that earth is a uniform sphere and its moment of inertia is I=`2/5MR^2`,where M=mass of earth and R = radius of earth.

Find the change in length of a day if the radius of earth changes by (1)/(2) % considering the mass constant. Assume that earth is uniform sphere and its moment of inertia is l = (2)/(3)MR^(2) , where M = mass of earth and R - radius of earth.

Keeping the mass constant , if the radius of the earth is halved, then the span of a day

If the radius of the earth-shrinks by 2% and its mass remain same, then calculate the value of g on the earth's surface.

If the radius of earth is halved and the mass is same then what will be the change of its acceleration due to gravity.

If the radius of the earth shrinks by1.5% then the value of acceleration due to gravity changes by

If the radius of the earth becomes half of the present radius , mass being constant, the weight of a body will be
