Question

Four identical thin, square metal sheets, S1, S2, S3 and S4, each of side a are kept parallel to each other with equal distance $d (≪ a)$ between them, as shown in the figure. Let $C_0 = \epsilon_0\frac{a^2}{d},$where $\epsilon_0$ is the permittivity of free space.

Match the quantities mentioned in List-I with their values in List-II and choose the correct option.

List-I	List-II
P	The capacitance between S1 and S4, with S2 and S3 not connected, is
Q	The capacitance between S1 and S4, with S2 shorted to S3, is
R	The capacitance between S1 and S3, with S2 shorted to S4, is
S	The capacitance between S1 and S2, with S3 shorted to S1, and S2 shorted to S4, is

• A. P → 3; Q → 2; R → 4; S → 5
• B. P → 2; Q → 3; R → 2; S → 1
• C. P → 3; Q → 2; R → 4; S → 1
• D. P → 3; Q → 2; R → 2; S → 5

Answer 1

Answer: (C)

P → 3; Q → 2; R → 4; S → 1

Answer 2

The correct option is (C):P → 3; Q → 2; R → 4; S → 1
