What would be the time period of rotation of earth so that the bodies at the equator would weight 40% of their actual weight?

What is the time period of rotation of the earth around its axis so that the objects at the equator becomes weightless? ( g=9.8 m//s^2 , radius of the earth =6400km )

Calculate the angular speed of rotation of the Earth so that the apparent g at the equator becomes half of its value at the surface. Also calculate the length of the day in this situation.

At what speed the volume of an object shrinks to half its rest value ?

It is known that if the length of the day were T0 hour, a man standing on the equator of the earth would have felt weightlessness. Assume that a person is located inside a deep hole at the equator at a distance of (R)/(2) rom the centre of the earth. What should be the time period of rotation of the earth for such a person to feel weightlessness? [R = radius of the earth]

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)

Show that if the earth were not rotating about its axis the value of g at the equator would exceed its present value by 3.36cm//s^(-2) . Given the radius of earth = 6.371xx 10^(6)m . and angular speed of earth =7.27xx10^(-5)rad//s^(-1)
