Determine the net capacitance C of each network of capacitors shown below. Assume that =1.0pF, =2.0pF,=4.0pF and =5.0pF. Find the charge on each capacitor, assuming there is a potential difference of 12.0V across each network.

Consider a charge (+5.0μC) fixed at a site with another charge (charge +3.0μC, mass 6.0μg) moving in the neighboring space. (a) Evaluate the potential energy of when it is 4.0 cm from . (b) If starts from rest from a point 4.0 cm from , what will be its speed when it is 8.0 cm from ? (Note:is held fixed in its place.
