JEE Main 30 January 2024, Shift 2, Physics Q42

Question 42 of 90 in this shift, Physics question 12 of 30, Section A.

Match List I with List II List I | List II A. Gauss's law of magnetostatics | I. ∮E⃗⋅da⃗=1εo∫ρdV\oint \vec{E}\cdot\vec{da} = \frac{1}{\varepsilon_o}\int \rho dV B. Faraday's law of electro magnetic induction | II. ∮B⃗⋅da⃗=0\oint \vec{B}\cdot\vec{da} = 0 C. Ampere's law | III. ∫E⃗⋅dl⃗=−ddt∫B⃗⋅da⃗\int \vec{E}\cdot\vec{dl} = \frac{-d}{dt}\int \vec{B}\cdot\vec{da} D. Gauss's law of electrostatics | IV. ∮B⃗⋅dl⃗=μ0I\oint \vec{B}\cdot\vec{dl} = \mu_0 I Choose the correct answer from the options given below:
  1. (1)A-IV, B-II, C-III, D-I
