2. A spherical insulator with a radius of 2 m has a volumetric charge density of p = A/r2, which would be a problem, except that a spherical hole with a radius of 0.5 m has been cut out of the middle of it. a. Find the total charge of the remaining hollow ball. b. Find the electric field at a distance of 1.0 m from the center of the sphere. Note: You will need to find the electric field for some arbitrary r < R, then plug in a value of r = 1.0 m into your final expression. c. Bonus: find the electric field at all points in space. This is easier than you think!

Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.
