Answer»

A conducting shell of inner radius $R_{1}$ and outer radius $R_{2}$ is given a charge $+ Q$ . A point charge $q_{1}$ is placed inside the shell and $q_{2}$ is placed outside the shell.

Then for various locations of $q_{1}$ and $q_{2}$ , match the following entries of column $- I$ with the entries of column $- II$ .

Column- $I$	Column- $II$
$(i) .$ If $q_{1}$ is at center and $q_{2} = 0$ , then $\to E$ at center of shell due to charge on outer surface of shell is	$(a) . \frac{q_{1}}{4 π ε_{0} r^{2}}$
$(ii) .$ If $q_{1}$ is at center and $q_{2}$ is at distance $r$ from the center, then $\to E$ at a point distant $r_{2}$ ( $> r$ ) from the center of the shell due to outer surface charge is	$(b) .$ Zero
$(iii) .$ If $q_{1}$ is not at center and $q_{2} = 0$ , then $\to E$ at point $P$ ( $P$ is at distance $r$ from $q_{1}$ due to charge of the inner surface of shell) is	$(c) .$ Cant be determined
