hey everyone just joined! glad to be here! i just don't get one part of the question and once i get it, i should be able to get the rest.
A battery with an emf of 20 volts is connected in series with a resistor of 300,0000 ohms and an air-filled parallel-plate capacitor of capacitance 6 microfarads.
The spacing between the capacitor plates is suddenly increased (in a time short compared to the time constant of the circuit) to four times its original value.
b. determine the work that must be done in increasing the spacing in this fashion.
thanks!
