The dimensional formula of the Universal constant of gravitation is

Options

A. `[M^(0)L^(-3)T^(-2)]`
B. `[ML^(-3)T^(2)]`
C. `[M^(-1)L^(3)T^(-2)]`
D. `[M^(2)L^(2)T^(2)]`

Answer

C

Explanation

Universal gravitational constant, `G = Fr^(2)/m_(1)m_(2) = [MLT^(-2)][L^(2)]/M^(2) = [M^(-1)L^(3)T^(-2)]`
