![a) A point charge +q is placed at the origin. By explicitly calculating the relevant line integral, determine how much exter- nal work must be done to bring another point charge +q from infinity to the point r2- ay? Consider the difference between external work and work done by the force. {2] b) Both of these charges are held fixed and a third charge +q is now brought from infinity to position F3 a+ay. Re- peat the same type of calculation as in a). What is the total stored potential energy of this three-charge system? 12 c) A fourth charge is now brought from infinity to 74-ai. Again, repeat the same type of calculation as in a).
