The force of attraction between two unit point masses separted by a unit distance is called

Options

A. gravitational potential
B. acceleration due to gravity
C. gravitational field
D. universal gravitational constant

Answer

D

Explanation

We know that, the gravitational force,

Where, F = Force between mass
m = Mass of the body
M = Gravitational Constant
r = Distant between two mass
Given, M = 1 unit, m = unit and r = 1, we get
`F=G(1xx1)/((1)^(2))rArrF=G`
Therefore , the force of attraction between two unit point massess separated by a unit distance is called universal gravitational constant.
