7. Figure below shows a +8.0 pC charge moving with a speed of 7.5 x 104 m/s parallel to a long straight wire. The wire is 6.50 cm from the charge and carries a current of 67.0 A in a direction opposite to that of the moving charge. | = 67.0 A q = +8.0 6.50 (a) Show the direction of the magnetic field and magnetic force acting on charge +q. (b) Calculate the magnitude and direction of the magnetic force acting on charge +q. (c) Indicate the direction of the magnetic field and magnetic force acting on charge +q if the current in the wire is reversed.
