NEET 2020 Physics Dimensional Analysis MCQ Question
Type: MCQ-conceptual-Easy-Class 11
Dimensions of stress are:
A
[ML⁰T⁻²]
B
[ML⁻¹T⁻²]
C
[MLT⁻²]
D
[ML²T⁻²]
Correct Answer
Option B
Detailed Explanation
Stress = Force / Area. Dimensions of force = [MLT⁻²], dimensions of area = [L²]. Therefore, dimensions of stress = [MLT⁻²]/[L²] = [ML⁻¹T⁻²]. The original explanation incorrectly computed the result as [ML⁰T⁻²] instead of [ML⁻¹T⁻²].
