Q 11-01-084JEE MainJEE Main 2025 (28 Jan, Shift 2)Easy
Match List-I with List-II.
**List-I**
(A) Angular impulse
(B) Latent heat
(C) Electrical resistivity
(D) Electromotive force
**List-II**
(I) $[M^0L^2T^{-2}]$
(II) $[ML^2T^{-3}A^{-1}]$
(III) $[ML^2T^{-1}]$
(IV) $[ML^3T^{-3}A^{-2}]$
Choose the correct answer from the options given below:
Answer: (D) (A)-(III), (B)-(I), (C)-(IV), (D)-(II)
- Angular impulse = change in angular momentum: $[ML^2T^{-1}]$ (III).
- Latent heat = energy per mass: $[L^2T^{-2}]$ (I).
- Resistivity $\rho = RA/l$, with $[R] = [ML^2T^{-3}A^{-2}]$: $[ML^3T^{-3}A^{-2}]$ (IV).
- Emf = work per charge: $\dfrac{[ML^2T^{-2}]}{[AT]} = [ML^2T^{-3}A^{-1}]$ (II).
(A)-(III), (B)-(I), (C)-(IV), (D)-(II).
