The bound volume charge density
Web(a)The volume charge density is given by ˆ b= r P = r (kxx^ + kyy^ + kz^z) = k(1 + 1 + 1) = 3k. So the total volume charge is Q v= 3k 4 3 ˇR3 = 4ˇkR3. The surface charge density is given by ˙ b= Pn^j surface = kR. So, the total surface charge is Q s= kR 4ˇR2 = 4ˇkR3. So, the total bound charge is Q= Q v+ Q s= 4ˇkR3 + 4ˇkR3 = 0, as expected. WebThe charge in terms of volume charge density is expressed as, ρ = q v Where, is the charge density q is the charge (C) v is the total volume in m 3 . Volume Charge Density Solved …
