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 rotaste so that the apparent g at the equator becomes zero? What wil 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.

If the earth stops rotating, the value of g at the equator will

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 ?

At which angular speed the earth should rotates so that the apparent weight of an object at equator will become zero ?

If the earth stops rotating, the value of ‘ g ’ at the equator will

A person stands on a spring balance at the equator. (a) How much is the reduction in weight as measured by the balance. (b) If the speed of earth's rotation is changed such that the balance reading is half of its true weight, what will be the length of the day in this case? (g=10m//s^(2),R_(e)=6400km)
