) Two long straight wires carrying 8 A of conventional current are connected by a three-quarter-circular arc of radius 0.0396 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 6×105 m/s as it passes through the center C of the arc, and at that instant the net force on the electron is zero. (Consider the charge of the electron: q = -1.6×10-19 C) Radius R C. Electron I The magnitude of the magnetic field due to the straight segments at the center of the arc is: straight B [T] 2.) The magnitude of the magnetic field due to the three-quarter-circular arc at the center of the arc is: Barc = [T] 3.
