NEET · Physics · STD 11 - 1. units,dimensions and measurement
dimensions of stress are
- A \(\left[ M L ^{-1} T ^{-2}\right]\)
- B \(\left[ M L T ^{-2}\right]\)
- C \(\left[ M L ^{2} T ^{-2}\right]\)
- D \(\left[ M L ^{0} T ^{-2}\right]\)
Answer & Solution
Correct Answer
(A) \(\left[ M L ^{-1} T ^{-2}\right]\)
Step-by-step Solution
Detailed explanation
stress \(=\frac{\text { Force }}{\text { Area }}\) \(=\frac{M^{1} L^{1} T^{-2}}{L^{2}}\)
