AP EAMCET · PHYSICS · Units and Dimensions
Of the following, the pair of physical quantities not having the same dimensional formula is
- A work and torque
- B angular momentum and Planck's constant
- C stress and linear momentum
- D surface tension and force constant
Answer & Solution
Correct Answer
(C) stress and linear momentum
Step-by-step Solution
Detailed explanation
Stress: \( \frac{F}{A} = \frac{[M L T^{-2}]}{[L^2]} = [M L^{-1} T^{-2}] \) Linear momentum: \( m v = [M] [L T^{-1}] = [M L T^{-1}] \) Stress and linear momentum do not have the same dimensional formula.
