What woluld be the length of a day. If angular speed of earth is increased such that bodies typing on the equator by off?

If the rotational speed of earth increase, then weight of body at the equator

What should be the angular speed of earth in radian/second so that a body of 5 kg weights zero at the equator? [Take g = 10 m//s^2 and radius of earth = 6400 km]

What should be the angular speed of earth in radian/second so that a body of 5 kg weights zero at the equator? [Take g = 10 m//s^2 and radius of earth = 6400 km]

What would be the angular speed of earth, so that bodies lying on equator may experience weightlessness ? ( g = 10m//s^(2) and radius of earth = 6400 km)

The angular speed of rotation of the earth is

The angular speed of rotation of the earth is

What would be the angular speed of earth, so that body lying on equator may appear weightless? ( g = 10 m//s^2 , radius of earth = 6400 km)
