Asked in JEE Main 12th April 1st Shift 2023 · Matching quantities to their dimensions
A: a spring constant is force per unit length, [MT⁻²], so (II).
B: angular speed is radians per second, [T⁻¹], so (I).
C: angular momentum is [ML²T⁻¹], so (IV).
D: moment of inertia is mr², [ML²], so (III).
Hence A-II, B-I, C-IV, D-III.
Reading this solution needs no sign-in. You only sign in to practise against the clock and keep your progress.
