Which of the following pairs of physical quantities have the different dimensions?

A

momentum and impulse

B

light year and time

C

energy and torque

D

none of the these

Text Solution

Verified by Experts

The correct Answer is:
B
Impulse=change in momentum (so dimension are same)
energy=force x displacement, torque `=vec(r)xxvec(F)`
both have same dimension
