Explanation Given data: The volume charge density is ρ v = 20 r z ( mC / m 3 ) . The range of r - coordinate is 0 ≤ r ≤ 2 m . The range of z - coordinate is 0 ≤ z ≤ 3 m . Calculation: The diagram for the given condition is drawn as shown in Figure 1. Write the standard expression of charge for volume charge density. Q = ∫ υ ρ v d υ (1) Here, Q is the charge contained in the cube. d υ is the differential volume. Differential volume in Cylindrical coordinate system is, d υ = r d r × d ϕ × d z Here, r is the radial distance. ϕ is the azimuth angle measured from positive x − axis. Substitute 20 r z for ρ v , r d r × d ϕ × d z for d υ , 0 for r 1 , 2 for r 2 , 0 for ϕ 1 , 2 π for ϕ 2 , 0 for z 1 , 3 for z 2 ,in equation (1)
