Q1.
Two isolated spherical conductors having radii 5 cm and 10 cm. They have charges of 12nC and -3nC respectively. Find the charges after they are connected by a conducting wire. Also, find the common potential after redistribution.
Ans. 3 nC, 6 nC, 540V
Q2.
Two parallel plate capacitors A and B having capacitance of 1μF and 5 μF are charged separately to the same potential of 100V. Now, the positive plate of A is connected to the negative plate of B, and the negative plate of A is connected to the positive plate of B. Find the final charges on each capacitor.
Ans. (200/3 μC), (1000/3) μC
