In this problem, we're going to consider Gauss's law:
, where E is the electric field, S is the surface area enclosing the net charge q, and ε0 is the permeability of free space.
In terms of volume charge density, we can express charge as:
, where V is the volume of the sphere.
Let R be the radius of the sphere and r the radius of the Gaussian surface.
The volume charge density:
The electric field at a distance of 0.144 m from the surface of a solid insulating sphere with a radius of 0.384 m is 1710 N/C.
A. Assuming the sphere's charge is uniformly distributed, what is the charge density inside it?
B. Calculate the electric field inside the sphere at a distance of 0.223 m from the center.
