Question

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

• A. (a) Mass, time
• A. (b) Time, length
• A. (c) Mass, length
• A. (d) Time, mole

Answer 1

(c)

Sol. Torque = $\lbrack ML^{2}T^{- 2}\rbrack$, Angular momentum= $\lbrack ML^{2}T^{- 1}\rbrack$ So mass and length have the same dimensions
