Find how many excess electrons must be distributed

Reference no: EM13704246

Solve the following questions:

Question I: How many excess electrons must be distributed uniformly within the volume of an isolated plastic sphere 30.0cm in diameter to produce an electric field of 1100N/C just outside the surface of the sphere?

Question II: What is the electric field at a point 11.0cm outside the surface of the sphere?

Include work and exact answer please! Thank you!
