Asolid 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?

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).

overcharge is the right answer system

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
