Problem 9: (30 points) Two long straight wires carrying 3 A of conventional current are connected by a three- quarter-circular arc of radius 0.0428 m. An electric field is also present in this region, due to charge not shown on the drawing. An electron is moving to the right with a speed of 5x 105 m/s as it passes through the center C of the arc, and at that instant the net electric and magnetic force on the electron is zero. (Consider the charge of the electron: q = -1.6×10¹9 C) Radius R C.P Electron
