nh
Thus the angular momentum (L) has the same dimensions as that of Planck's constant (h)
(B) : Impulse I=ΔP
Thus impulse (I) has the same dimensions as that of linear momentum (P)
(C) : Using τ=Iα ⟹ I=

where angular acceleration is not dimensionless.
Thus the dimensions of moment of inertia are different from those of moment of force

Hence, torqua and energy have same dimensions.Which of the following pairs has same dimensions?
1) Angular momentum of Plank's constant
2) Dipole moment and electric field
3) Both 1 and 2
4) None of theseANSWER
A & B are two sets
AᴜB = (A-B) + (A∩B) + (B-A)
