The force of attraction between two unit point masses separated by a unit distance is called
पर्याय
gravitational potential
acceleration due to gravity
gravitational field
universal gravitational constant
Advertisements
उत्तर
universal gravitational constant
Explanation:
F = `"G"("m"_1"m"_2)/"d"^2`
F = G, i.e., the force of attraction between two unit point masses separated by a unit distance is a universal gravitational constant.
