	When a body is taken from the equator to the poles, its weight
	A body of mass m is taken to the bottom of a deep mine. Then
	A body weighs 700 gm wt on the surface of the earth. How much will it weigh on the surface of a planet whose mass is $\frac{1}{7}$ and radius is half that of the earth
	In order to find time, the astronaut orbiting in an earth satellite should use
	A spherical planet far out in space has a mass ${M_0}$ and diameter ${D_0}$. A particle of mass m falling freely near the surface of this planet will experience an acceleration due to gravity which is equal to
	If the earth stops rotating, the value of ‘g’ at the equator will
	The mass and diameter of a planet have twice the value of the corresponding parameters of earth. Acceleration due to gravity on the surface of the planet is
	As we go from the equator to the poles, the value of g
	Force of gravity is least at
	The radius of the earth is 6400 km and $g = 10m/{\sec ^2}$. In order that a body of 5 kg weighs zero at the equator, the angular speed of the earth is
