Solution
The correct option is D
universal gravitational constant
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.
It is denoted by ‘G’.
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.
