Unequal Dimensions Pair – Rankers Physics

Dimensions: Practice Problem & Solution

Which pair have not equal dimensions? [2000]
Energy and torque
Force and impulse
Angular momentum and Planck's constant
Elastic modulus and pressure

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Dimensions. Understanding the underlying formula is key to arriving at the correct answer below:

Force has dimensions \(MLT^{-2}\) and impulse has dimensions \(MLT^{-1}\). These are not equal.
