What is charge density.

This is perhaps easier to explain by splitting the calculation in two steps. The solid ball of charge is supposed to be homogeneous, so it has a charge density. ρ = total charge total volume = q 4π 3 R3. ρ = total charge total volume = q 4 π 3 R 3. The smaller sphere has volume Vr = 4π 3 r3 V r = 4 π 3 r 3, and therefore has charge.From measurements of B and t, nq can be determined, and from q = ±e, the charge carrier density n can be determined.
