Electric Field with Greatest Distance from Center of Sphere

APPHEM-VWKOAK

Two sphere's are isolated from each other. They each have an identical net positive charge and have the same radius, however, 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 distance $x$ from the center of the spheres?

Assume $x$ is less than the radius of the spheres.

A

The conducting hollow sphere has a greater E-field.

B

The insulating solid sphere has a greater E-field.

C

Both spheres have the same E-field.

D

Neither sphere would cause there to be an Electric field.

E

The electric field would be infinite because it is being measured​ at less than the radius of the sphere.
