Which of the following pairs have different dimensions?

A

`Frequency and angular velocity.

B

Tension and surface tension.

C

Density and energy density.

D

Linearmomentum and angular momentum.

Text Solution

Verified by Experts

The correct Answer is:
B, C, D
Frequency and angular velocity have the same dimension `[T^(-1)]`.
Tension has dimensions of force and surface tension has dimensions of `"force"//"length"`. Density has dimensions of `"mass"//"volume"` and energy density has dimensions of `"energy"//"volume"`. Angular momentum has dimensions of linear momentum `xx` distance.
