Question 222: 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.
