The quantity G depends on the local value of g, acceleration due to gravity
The quantity G is greatest at the surface of the Earth
The quantity G is used only when · earth is one of the two masses
The quantity G is a universal constant

Assertion : A body weighs less on a hill top than on the Earth's surface e\'en though its mass remains unchanged.
Reason : The acceleration clue to gravity of the Earth decreases with height.

` G = g M/R^2`
` g = G M/R^2`
` M = (gG)/R^2`
` R = (gG)/M^2`

gravitational pull on the paper is less than the coin
buoyant force on the piece of paper is more than that on the coin
buoyant force on the coin is more and acts in the downward direction
the piece of paper takes a longer path to reach the ground

Assertion : Two artificial satellite having different masses and revolving around the Earth in the same circular orbit have same speed.
Reason : The speed of a satellite is directly proportional to the radius of its orbit.
