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

The radius of the earth is 6400 km and g=10m//sec^(2) . In order that a dody of 5 kg weight zero at the equator, the angular speed of the earth is

The radius of the Earth is 6400 km and g = 10 in order that a body of 5 kg weights zero at the equator, the angular speed of the Earth is ............ rad

Determine the speed with which the earth would have to rotate on its axis so that a person on the equator would weigh 3//5 the as much as at present. Take the equatorial radius as 6400 km.

Determine the speed with which the earth have to roate on its axis so that a person on the equator would weigh 2//5th as much as at present. Take the equatorial radius as 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.
