A sphere with radius 10 cm is filled with a uniform charge distribution. The magnitude of the electric field at a point 5 cm from the center of the sphere is 3014 N/coul. Use this fact to calculate the charge density ρ inside the sphere.

What is a costume plot? why is it important to a film or theater production?
