Question

In the circuit given below, the charge in µC, on the capacitor having capacity 5 µF is

(a) 4.5 

(b) 9 

(c) 7 

(d) 15

Answer 1

Correct option: (b) 9

Explanation: 

Potential difference across the branch de is 6 V 

Net capacitance of de branch is 2.1 µF

Potential across 3 µF capacitance is

Potential across 2 and 5 combination in parallel is 6 -  4.2 = 1.8 V
