Question

The dimensions of acceleration due to gravity are _____

(a) [M^0L^1T^-2]

(b) [M^1 L^-1T^-2]

(c) [M^-1 L^2 T^-1]

(d) [M^0L^-1T^2]

The question was posed to me in semester exam.

My question comes from Acceleration due to Gravity of the Earth in chapter Gravitation of Physics – Class 11

Answer 1

The correct choice is (a) [M^0L^1T^-2]

Easy explanation: The unit of acceleration is m/s^2.

m/s^2 = [L^1 T^-2]

= [M^0 L^1 T^-2].
