Show that if the earth stops rotating about its axis, then the acceleration due to gravity at the equator will increase by `3.38 cm *s^(-2)`. The radius of the earth`=6.4 xx10^8 cm`.

Suppose the earth stops rotating about its axis. What will be the effect on the weight of bodies ?

The height vertically above the earth's surface at which the acceleration due to gravity becomes 1% of its value at the surface is (R is the radius of the earth)

For what value of the angular velocity of the earth, the acceleration due to gravity in the equatorial region would have been zero ? The average density of the earth's material =5.5 g*cm^(-3) and G=6.67xx10^(-8) CGS unit. Find the ratio of this calculated value and the present value of the angular velocity of the earth.

At what height above the surface of the earth will the acceleration due to gravity be one-fourth of its value on the surface of the earth ?[Radius of the earth =R]

At what height above the surface of the earth will the acceleration due to gravity be half of its value on the earth's surface ? Radius of the earth =6400 km.

What is the difference in the values of acceleration due to gravity at the polar region and at the equator due to the diurnal motion of the earth ? Radius of the earth=6400 km.

What will be the velocity of rotating of earth about its own axis so that a body becomes weightless at the equator ?
