Easy MCQ +4 / -1 PYQ · JEE Mains 2025

Match List - I with List - II.

List - I List - II
(A) Electric field inside (distance r > 0 from center) of a uniformly charged spherical shell with surface charge density σ, and radius R. (I) σ/ε0
(B) Electric field at distance r>0 from a uniformly charged infinite plane sheet with surface charge density σ. (II) σ/2ε0
(C) Electric field outside (distance r>0 from center) of a uniformly charged spherical shell with surface charge density σ, and radius R. (III) 0
(D) Electric field between 2 oppositely charged infinite plane parallel sheets with uniform surface charge density σ. (IV) $\frac{\sigma}{\epsilon_0 r^2}$

Choose the correct answer from the options given below :

  1. A <p>(A)-(IV), (B)-(I), (C)-(III), (D)-(II)</p>
  2. B <p>(A)-(II), (B)-(I), (C)-(IV), (D)-(III)</p>
  3. C <p>(A)-(III), (B)-(II), (C)-(IV), (D)-(I)</p> Correct answer
  4. D <p>(A)-(IV), (B)-(II), (C)-(III), (D)-(I)</p>

Solution

<p>(A) $\rightarrow 0$ (III)</p> <p>(B) $\rightarrow \frac{\sigma}{2 \varepsilon_0}$</p> <p>(C) $\rightarrow \frac{\sigma \mathrm{R}^2}{\varepsilon_0 \mathrm{r}^2}$ (No row matching)</p> <p>$(\mathrm{D}) \rightarrow \frac{\sigma}{\varepsilon_0}(\mathrm{I})$</p>
