Question

The force of attraction between two unit point masses separated by a unit distance is numerically equal to

Options

• acceleration due to gravity.

• gravitational potential.

• universal gravitational constant.

• gravitational intensity.

Answer 1

universal gravitational constant.

Explanation:

According to Newton's law of gravitation,

F = `(GM_1M_2)/r^2`

If M₁ = M₂ = 1 unit of mass and

r = 1 unit of distance, then

F = G = universal gravitational constant.
