Asked in CBSE AIPMT 2000 · Pairs with the same dimensions
Idea: the odd pair is the one whose two members differ by a factor of time.
[force]=[MLT⁻²]
[impulse]=[F t]=[MLT⁻²][T]=[MLT⁻¹]
These differ by [T], so force and impulse are not equal.
Energy and torque are both [ML²T⁻²], angular momentum and h are both [ML²T⁻¹], and elastic modulus and pressure are both [ML⁻¹T⁻²].
Reading this solution needs no sign-in. You only sign in to practise against the clock and keep your progress.
