B. The earth and the sun only

C. Any two bodies having some mass

D. Any two charged bodies only

Two objects of different masses falling freely near the surface of moon would:

A. Have same velocities at any instant

B. Have different accelerations

C. Experience forces of same magnitude

D. Undergo a change in their inertia

The value of acceleration due to gravity of earth:

A. Is the same on equator and poles?

B. Is the least on poles?

C. Is the least on equator?

D. Increases from pole to equator

The value of quantity G in the formula for gravitational force:

A. Depends on mass of the earth only

B. Depends on the radius of earth only

C. Depends on both mass and radius of earth

D. Depends neither on mass nor on radius of earth

Two particles are places at some distance from each other. If, keeping the distance between them unchanged, the mass of each of the two particles is doubled, the value of gravitational force between them will become:
