Suppose the charge density along a wire is given by X(x, y, z) = bx² + cy³ for constants band c. Furthermore, the wire follows the path C with parametric equations x = R cost,y = Rsint and z = mt for constants m, R and 0 ≤ t ≤ 2π. Find the net charge on C bycalculating the integral with respect to arclength fo Ads.
