A non-uniformly charged semicircle of radius R=10.9 cm lies in the xy plane, centered at the origin, as shown. The charge density varies as the angle θ (in radians) according to λ=1.15θ, where λ has units of  μC. What is the y component of the electric field at the origin? I have already found the total charge to be 6.186E-7 C.
