JEE MAIN - Physics (2025 - 29th January Morning Shift - No. 24)
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 :
(A)-(IV), (B)-(I), (C)-(III), (D)-(II)
(A)-(II), (B)-(I), (C)-(IV), (D)-(III)
(A)-(III), (B)-(II), (C)-(IV), (D)-(I)
(A)-(IV), (B)-(II), (C)-(III), (D)-(I)
Explanation
(A) $\rightarrow 0$ (III)
(B) $\rightarrow \frac{\sigma}{2 \varepsilon_0}$
(C) $\rightarrow \frac{\sigma \mathrm{R}^2}{\varepsilon_0 \mathrm{r}^2}$ (No row matching)
$(\mathrm{D}) \rightarrow \frac{\sigma}{\varepsilon_0}(\mathrm{I})$
