If a man at the equator would weight (3/5)th of his weight, the angular speed of the earth is:

If a man at the equator would weigh (3//5) th of his weight, the angular speed of the earth is

The angular speed of rotation of the earth is

With what speed should the earth rotate in order that the weight of a man on the equator is reduced to half his present weight , if the radius of the earth is 6400km.

Find the value of angular velocity of axial rotation of the earth, such that weight of a person at equator becomes 3/4 of its weight at pole, Radius of the earth at equator is 6400 km.

Calculate the height at which a man's weight becomes ( 4//9) of his weight on the surface of the earth, if the radius of the earth is 6400km.

If the earth has no rotational motion, the weight of a person on the equation is W. Detrmine the speed with which the earth would have to rotate about its axis so that the person at the equator will weight (3)/(4) W. Radius of the earth is 6400 km and g = 10 m//s^(2) .

If the earth has no rotational motion, the weight of a person on the equation is W. Detrmine the speed with which the earth would have to rotate about its axis so that the person at the equator will weight (3)/(4) W. Radius of the earth is 6400 km and g = 10 m//s^(2) .

If the diameter of the earth becomes two times its present value and its mass remains unchanged then how would the weight of an object on the surface of the earth be affected ?

Why does a body lose weight at the centre of the earth?

The angular speed of earth around its own axis is
