Electrostatics 6 Question 1

1. A circuit is connected as shown in the figure with the switch S open. When the switch is closed, the total amount of charge that flows from Y to X is

(2007,3M)

(a) zero

(b) 54μC

(c) 27μC

(d) 81μC

Show Answer

Answer:

Correct Answer: 1. (c)

Solution:

  1. From Y to X charge flows to plates a and b.

(qa+qb)i=0,(qa+qb)f=27μC

Initial figure (when switch was open)

Final figure (when switch is closed) 27μC charge flows from Y to X.

Correct option is (c).
