Challenge Problem: Circular Arc of Charge
Click here to see the solution
     In this problem there is a circular arc of charge, uniformly distributed along its length. Each element of charge is at a different angle, θ, from the vertical axis. Your goal is to find the E-Field at the origin given the parameters shown below. Clue: If you call the arc length L, the width of dq is Rdθ.
