Which one of the following pairs has the same dimensions ?
A. Torque and Force
B. Energy and Acceleration
C. Light Year and Wavelength
D. Velocity and Momentum

Answer 1

Correct Answer - c
Both light year and wavelength denote lengths or distances and they have the same dimensional equation of `[M^(0)L^(1)T^(0)]`. (a), (b) and (d) are different physical quantities.
