Which of the following physical quantities do not have same dimensions ?

Options

A. Pressure and stress
B. tension and surface tension
C. strain and angle
D. energy and work.

Answer

B

Explanation

Pressure and stress both have the dimensions of force/are. Strain and angle are both dimensionsless. Energy and work have the same dimensions force `xx` distance. Tension and surface tension refer to two different physical quantities and their dimensions are different. Tension is a force and surface tension is force per unit length.
