Q1. Two point charges = 2.10 and = -6.40 are 0.100 apart. Point is midway between them; point is 0.080 from and 0.070 from. Take the electric potential to be zero at infinity.

Q2. A non-conducting spherical shell - inner radius a, outer radius b, has a volume charge density r=r0cos(er/b). The force on a point charge Q located at the center of the shell is 0 why?

Q3. A charge of +2.ooX10^-9 C is placed at an origin, and another charge of +4.ooX10^-9 C is placed at x= 1.5m. Find out the point between these two charges where a charge of +3.00X10^-9 must be placed so that the net electric force on it is zero.
