alleryFor relation v = u + at, dimensional consistency requires:
AAll terms must have same dimensions LT⁻¹
BCannot check
C[v] = [u] = [at]
DRandom
Answer & Solution
Correct answer: A. All terms must have same dimensions LT⁻¹
[v] = LT⁻¹, [u] = LT⁻¹, [at] = LT⁻² × T = LT⁻¹.
✓ All terms have same dimensions (velocity).
Any equation that adds quantities must have dimensional consistency.
