If the speed of rotation of earth about its axis increases, then the weight of the body at the equator will

If the speed of rotation of earth about its axis is increased,

The rotation of earth about its axis is

The rotation of earth about its axis is………..

What should be the angular velocity of rotation of Earth about its own axis so that the weight of body at the equator reduces to 3/5 of its present value? (Take R as the radius of the Earth)

The acceleration due to gravity at the poles is 10ms^(-2) and equitorial radius is 6400km for the earth. Then the angular velocity of rotation of the earth about its axis so that the weight of a body at the equator reduces to 75% is

The angular speed of rotation of earth about its axis at which the weight of man standing on the equator becomes half of his weight at the poles is given by

The angular speed of rotation of earth about its axis at which the weight of man standing on the equator becomes half of his weight at the poles is given by
