Which is greater , the angular velicty of the hour hand of a watch or angular velocity of earth around its own axis ?

What is the angular velocity of the earth?

What should be the angular velocity of earth about its own axis so that the weight of the body at the equator would become 3/4 th of its present value ?

If omega_(E ) is the angular velocity of the earth rotating about its own axis and omega _(H) is the angular velocity of the hour of a clock , then

If omega_E and omega_H are the angular velocities of the earth rotating about its own axis and the hour hand of the clock respectively, then

If x_(1) is the magnitude of gravitational potential excatly midway between earth and surface and x_(2) is the square of angular velocity of rotation of earth around its own axis such that alll bodies equator are in square of angular velocity of rotation of earth around its own axis such that al bodies equator are in floating position. Now if (x_(1))/(x_(2))=[1+(3)/(x)]R^(2) . Find the value of x.
