Questions
In the arrangement will be the potential difference between the terminals A and B after the battery is removed and the switch S is closed ?
detailed solution
Correct option is A
Total charge stored in the system is Q = 10×3×2+43+2+4μC=20μCafter the battery is removed and S is closed, total charge in the system between A and B, is Q1 = Q = 20µC∴VAB=Q'2+4volt=206volt=3.33voltSimilar Questions
Two identical metal plates are given positive charges Q1 and Q2 (<Q1) respectively. If they are now brought close together to form a parallel plate capacitor with capacitance C, the potential difference between them is
