A hollow sphere of radius a has uniform
surface charge density σ and is centered at the origin. It
sits inside a bigger sphere, also centered at the origin, with
radius b > a and uniform
surface charge density −σ. Because of the spherical
symmetry, the electric field will have the form () =

negative E(r) corresponds to an
electric field pointing towards the origin, and positive
E(r) corresponds to a field
pointing away. What is E(r)...

Charge Q is uniformly distributed inside a sphere of radius R. (a) Determine the electric field inside and outside the sphere. Explain how you arrive at the answer. (b) A cavity of radius R/4, and centered at a point a distance R/2 from the center of the sphere, is made within the sphere. This means that within the sphere of radius R, there is a smaller sphere of radius R/4 which has no charge (the charge density is zero within...
