Question 237: Units , Dimensions and Error Analysis

Question

The physical quantities not having same dimensions are

Accepted Answer

Momentum = mv = [${M{L}{T^{ - 1}}}$]
Planck's constant, h = ${E \over v}$ = ${[{M{L^2}{T^{ - 2}]}} \over {[{T^{ - 1}}]}}$ = $[{M{L^2}{T^{ - 1}}}]$
So Momentum and Planck's constant do not have same dimensions.

Answer

torque and work
