Question

The dimensions of universal gravitational constant are

(a) [M^-1L³T^-2]

(b)   [ML²T^-1]

(c) [M^-2L³T^-2]

(d) [M^-2L²T^-1]

Answer 1

Correct Option (a) [M^-1L³T^-2]

Explanation:

 Gravitational constant G

= force x (distance)²/mass x mass

Dimcnsions of  G = [MLT^-2][L²]/[M][M] = [M^-1L³T^-2]
