Question

Q:

Four capacitors are connected as shown in the figure where V = 10V, C1 = 3muF, C2 = 6muF, C3 = 2muF, and C4 = 2muF. Please specify units carefully. Find the equivalent capacitance of the arrangement. After charging, find the stored stored energy in each of 4 capacitors. What is the potential difference across each of 4 capacitors ? Find the stored charge in each of 4 capacitors. A cylindrical capacitor is composed of an inner conducting cylindrical shell which has a radius r1 and the outer shell with a radius r2. Positive charge Q is placed on the inner shell while negative charge - Q is placed on the outer shell. Two conducting cylindrical shells have same length L. Find the expression for the capacitance of the cylindrical capacitor. A particle that has mass m and positive charge q is placed right next to the inner shell with zero initial velocity. The particle will be repelled by the positively charged inner shell. Find the velocity of the particle when it reaches the outer shell. The cylindrical capacitor is to be designed to store 1 nC of charge when 100K battery is connected. For r1 = 5 cm and L = 10 m, find r2 to satisfy the design criteria.
