Question

The fundamental physical quantities that have same dimensions in the dimensional formulae of torque and angular momentum are 

(A) mass, time 

(B) time, length 

(C) mass, length 

(D) time, mole

Answer 1

Answer is (C) mass, length

Torque = [M¹ L² T^-2], 

Angular momentum = [M¹ L² T^-1] 

So mass and length have the same dimensions.
