Q.
Two spheres are isolated from each other. They each have an identical net positive charge and the same radius. One sphere is solid and insulating while the other is a hollow conducting sphere whose charge is uniformly distributed.
For which sphere is the electric field the greatest at a distance x from the center of the spheres? Assume x is greater than the radius of the spheres.
