Question

A solid cylinder of length L and radius R is made of an insulating material. This cylinder holds a net charge of Q that is evenly distributed throughout the cylindrical volume. What is the volume charge density, rho, of this charged cylinder?

Answer 1

Answer: ρ= Q/(π*R^2*L)

Explanation: The volume of the solid cylinder is given by: π*R^2*L

so the  volume charge density, ρ, is defined as Q/Volume of the cylinder

thus  ρ= Q/(π*R^2*L).
