Please write your work neatly so I could understand it
3. A very long, straight line of charge runs parallel to a verylarge, planar sheet of charge. The 2 charge density of the line is-2.0 nC/cm and that of the sheet is +0.50 nC/cm^2 . Thedistance
between the line and the sheet is 8.0 cm. An electron isreleased at rest, at a location that is halfway between the lineand the sheet. Use conservation of energy to calculate the speed ofthe
electron when it strikes the sheet. (Hint: calculate thepotential difference due to line only and then the potentialdifference due to the sheet only, and add them up to get thepotential difference
you need to determine the speed)
4. You have three capacitors, of 10 nF, 20 nF and 30 nFcapacitances, and a voltage source of 11
Volts.
A. Connect the capacitors in series and apply the voltage acrossthe network. Calculate the equivalent capacitance of the network,the charge stored in the network, the energy stored in the
network, and the voltage across each capacitor.
B. Connect the capacitors in parallel and apply the voltageacross the network. Calculate the equivalent capacitance of thenetwork, the charge stored in the network, the energy stored inthe
network and the charge stored in each capacitor.
