NEET 2014 Physics Dimensional Analysis MCQ Question
Type: MCQ-conceptual-Medium-Class 11
If force (F), velocity (V) and time (T) are taken as fundamental units, then the dimensions of mass are
A
[FV⁻¹T]
B
[FVT⁻²]
C
[FV⁻¹T⁻¹]
D
[FV⁻¹T]
Correct Answer
Option A
Detailed Explanation
Using dimensional analysis, [M] = [F][V]⁻¹[T], since F = ma and V = LT⁻¹, we have [M] = [FV⁻¹T].
