A body weighs 49 N on a spring balance at the north pole. What will be its weight recorded on the same weighing machine, if it is shifted to the equator ?
(Use `g =(GM)/R^2=9.8 ms^(-2)` and radius of earth, R = 6400 km.]

A body weights 98 N on a spring balance at the north pole. What will be its weight recorded on the same scale if it is shifted to te equator? Use g= GM/R^2=9.8m/s^2 and the radius of the earth R=6400 km.

The reading of a spring balance corresponds to 100 N while situated at the north pole and a body is kept on it. The weight record on the same scale if it is shifted to the equator, is (take, g = 19 " ms"^(2-) and radius of the earth, R = 6.4 xx 10^(6) m)

A simple pendu,um has a time eriod exactly 2 s when used i a laboratory at north pole. What wil be the time period if the same pendulum is used in a labroator at equator? Ccount for the earth's rotation only. Take g=(GM)/R^2=9.8ms^-2 and radius of earth =6400 km

Suppose the earth increases it speed of rotation. At what new time period will the weight of a body on the equator becomes zero ? (Take, g = 10 ms^(-2) and radius of earth R = 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]

If weight of an object at pole is 196 N then weight at equator is [ g = 10 m/s^2 , radius of earth = 6400 Km]

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 )

In order to make the weight of a 5kg body to zero at the equator. The angular speed of the earth would must be (take, g = 10m//s^(2) and radius of the earh, R = 6400 km)

Calculate the acceleration due to gravity at a height of 1600 km from the surface of the Earth. (Given acceleration due to gravity on the surface of the Earth g_(0) = 9.8 ms^(-2) and radius of earth, R = 6400 km).

Suppose the earth increases its speed of rotation . At what new time period will the weightof a body on the equator becomes zero? Take g=10 m/s^2 and radius of the earth R=6400 km .
