JEE Mains · Physics · STD 12 - 2. Electric potential and capacitance
In the given figure the total charge stored in the combination of capacitors is \(100\,\mu C\). The value of ' \(x\) ' is \(............\).
- A \(5\)
- B \(10\)
- C \(15\)
- D \(20\)
Answer & Solution
Correct Answer
(A) \(5\)
Step-by-step Solution
Detailed explanation
Charge on \(C_1\) is \(Q_1=2 \times 10=20\,\mu C \dots(i)\) Charge on \(C _2\) is \(Q _2= x \times 10=10\,x \mu C \dots(ii)\) Charge on \(C _3\) is \(Q _3=3 \times 10=30\,\mu C \dots(iii)\) Total charge \(20+10 x +30=100\) \(\Rightarrow x =5\)
