AP EAMCET · PHYSICS · Mechanical Properties of Solids
Among the following, the physical quantity having the dimensions of Young's modulus is
- A strain
- B gravitational potential
- C surface energy
- D energy density
Answer & Solution
Correct Answer
(D) energy density
Step-by-step Solution
Detailed explanation
Dimensions of Young's modulus: \([ML^{-1}T^{-2}]\) Dimensions of energy density: \(\frac{\text{Energy}}{\text{Volume}} = \frac{[ML^2T^{-2}]}{[L^3]} = [ML^{-1}T^{-2}]\) energy density
