In the adjoining figure, the potential difference between \(X\) and \(Y\) is 60 V. The potential difference between the points \(M\) and \(N\) will be 
- A \(10 \mathrm{V}\)
- B \(15 \mathrm{V}\)
- C \(20 \mathrm{V}\)
- D \(30 \mathrm{V}\)
Answer & Solution
Correct Answer
(D) \(30 \mathrm{V}\)
Step-by-step Solution
Detailed explanation
Capacitors in series \(2 C_{1} \times V_{1}=C \times V_{2}\) \(2 V_{1}=V_{2} \ldots\) (i) and \(V_{1}+V_{2}+V_{1}=60 \ldots\) (ii) Solving Eqs. (i) and (ii), we get \(V_{2}=30 \mathrm{~V}\)
