VL? x2 (i.e., the A wire sits in the ry-plane coinciding with the semicircular curve y = v top half of a circle of radius L). The wire has lineal charge density (i.e., charge per unit length) given by A(x, y) = Ao- L3 with Ao and L constant. Determine the total charge, Q, on the wire in terms of L and Ao.
