Answer & Solution
Correct Answer
(A) (A)-(III), (B)-(II), (C)-(IV), (D)-(I)
Step-by-step Solution
Detailed explanation
Inside uniformly charged spherical shell, \(E=0\) \(\therefore \mathrm{A} \rightarrow \mathrm{III}\) For uniformly charged infinite plate \(E=\frac{\sigma}{2 \varepsilon_0}\) \(\therefore \mathrm{B} \rightarrow \mathrm{II}\) Outside of spherical shell…
