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 universal gravitational constant

• Soln:

Answer is (d) universal gravitational constant

Explanation:

F= Gx𝑚1𝑥𝑚2

𝑟2

Here point masses are separated by unit distance Hence m1, m2 and r = 1

Hence F=G which is a universal constant hence answer is universal gravitational constant
