1) An insulating rod of length L=8.15 cm is uniformly charged with q=-4.23 fC. (a) What is the linear charge density of the rod? (b) what is the electric field at point P (it's a vector, so both magnitude and direction!). P is a=12.0 cm away from the end of the rod. Work it out! Don't just quote the special case formula, I want to see you you do it from scratch. (c) what is the answer if "a" was 50 m instead? (d) at 50 m, what if it wasn't a rod but a poínt charge with the same "q"? -4 P L 2) You've got an electric dipole in an electric field of magnitude 46.0 N/C. You want to flip it 180 degrees from where it started (it starts pointing at an angle of 64 degrees from the electric field). The electric dipole moment of this thing is 3.02x10-25 Cm (magnitude: direction described above). How much work do you do while cranking it around?
