At what rate should the earth rotate so that the apparent g at the equator becomes zero? What will be the length of the day in this situation?

At what rate should the earth rotate so that the apparent g at the equator becomes zero? What will be the length of the day in this situation?

(a) At what rate should the earth so that the apparent g at the equator becomes zero? What will be the length of the day in this situation? (b) A body stretches a spring by a particular length at the earth's surface at equator. At what height above the south pole will it stertch the same spring by the same length? Assume the earth to be spherical.

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.

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.

How mcuh faster than its present rate should the earth rotate about its axis so that the weight of a body at the equator becomes zero? Also calculate the new length of the day. (c ) What would happen if rotation becomes faster ?

If the earth losses the atmosphere what will happen to the length of the day?

How many times faster than its present speed the earth should rotate so that the apparent weight of an object at equator becomes zero ? Given radius of the earth = 6.37 xx 10^(6) m . What would be the duration of the day in that case ?
