Problem 30294.
A flat air capacitor with a capacity C = 1.1 * 10^-8 F is charged to a potential difference of 300 V. After disconnecting from the voltage source, the distance between the capacitor plates was increased five times. Determine: 1) the potential difference on the capacitor plates after they are moved apart; 2) the work of external forces to move the plates apart.
Detailed solution with a brief record of the conditions, formulas and laws used in the solution, derivation of the calculation formula and answer.
