A 14 cm length of wire carries a current of 1.9 A in the positive z direction. The force on this wire due to a magnetic field B is f* = (-0.2 1 + 0.2 Ĵ) N. If this wire is rotated so that the current flows in the positive x direction, the force on the wire is f* = 0.2 k N.

Q2: In a cathode ray oscilloscope, 100 electrons are moving with a speed of 8.0 x106 m/s horizontally andpasses through the neck tube coils which creates a magnetic field of 25 mT. If It experiences a magneticforce of 2.8 X10-14 N, how can you predict the angle of motion of charges? If the charges are stationary,can the field produce magnetic force on these charges? If these charges are moving in an electric field, canit produce a force? Justify your answer for both cases.(Charge of electron=1.6 x 10-19 C.)

6. Refer to the diagram For the moment please disregard the moving charge off to the right. The diagram above shows segments of two long straight wires, carrying currents I_1 = 3.97 A and I_2 = 2.88 A respectively. The distance between the wires is 1.99 cm. What is the force on a 5.57-cm segment of wire #2 due to the magnetic field from wire #1?   5.12E-06 N   7.68E-06 N   1.09E-05 N   6.40E-06 N

A magnetic field has a magnitude of 0.0016 T, and an electric field has a magnitude of 6.4 x 103 N/C. Both fields point in the same direction. A positive 1.7-µC charge moves at a speed of 4.2 x 106 m/s in a direction that is perpendicular to both fields. Determine the magnitude of the net force that acts on the charge.
