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

Options

  1. Apressure and stress
  2. Btension and surface tension
  3. Cstrain and angle
  4. Denergy and work.

Correct answer

B. tension and surface tension

Step-by-step solution

Pressure and stress both have the dimensions of force/area. Strain and angle are both dimensionsless. Energy and work have the same dimensions force ( ) 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.
