### HC Verma Solutions of Ch-31  Vol-2 Concept of Physics for Class-12

(Page-164)

#### Question-1 :-

A capacitor of capacitance C is charged to a potential V. The flux of the electric field through a closed surface enclosing the capacitor is

(a) CV/∈ο

(b) 2CV/∈ο

(c) CV/2∈ο

(d) Zero

The option (d) Zero is correct
Explanation:

Since the net charge enclosed by the Gaussian surface is zero, the total flux of the electric field through the closed Gaussian surface enclosing the capacitor is zero.

#### Question-2 :-

Two capacitors each having capacitance C and breakdown voltage V are joined in series. The capacitance and the breakdown voltage of the combination will be

(a) 2 C and 2 V

(b) C/2 and V/2

(c) 2 C and V/2

(d) C/2 and 2 V.

The option (d) C/2 and 2 V.is correct
Explanation:

Since the voltage gets added up when the capacitors are connected in series, the voltage of the combination is 2V.

Also, the capacitance of a series combination is given by

Here ,

C_net = Net capacitance of the combination

C= C2 = C

∴ Cnet = C/2
