A conductive sphere has a total charge Q uniformly distributed over its surface except
at a point A, where there is no charge. Assuming that the point A has a 1/50 of the total area of the sphere.
a) find an expression for the total electric field of the system on the axis between the center
of the sphere and the center of the point A.
b) calculate the electric filed at points r = 0, r = 0.9R, r = 1.2R.
(Data: Q = 4x10^-6 C; R = 0.25 m.)

A total charge Q is uniformly distributed over the surface of two concentric con- ductive spheres of radii Ri R2 with the same density σ. To be clear, qi is on the smaller sphere, g2 on the larger sphere, and Q2. What are the electric field and the potential everywhere? What is the value of Q if one needs 10.J of work to move a positive charge of 1Coulumb from infinity to the center of the くHo spheres?
