Question

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

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

Answer 1

The correct option is D

universal gravitational constant

1. The force of gravitational attraction between two objects of a unit mass each, that are separated by a unit distance is called the universal gravitational constant.
2. It is denoted by ‘G’.
3. Its value is 6.67 x 10^-11 Nm² kg^-2 and it is a constant everywhere in the universe.

Hence, the answer is (D) universal gravitational constant.
