The plane of a 5.0cm x 8.0cm rectangular loop of wire is parallel to a 0.5 T magnetic field. The loop carries a current of 5.4 A . What torque acts on the loop? Note: It does not matter it you take B along the 5 cm or the 8 cm side of the loop. The result will be the same. The torque may be about an axis situated in the plane of the rectangle and passing through the middle of the rectangle. In the circuit shown in the figure find the current through the 10 Ohm resistor. The emfs of the two batteries are E1 =14 V and E2=7 V . Note: depending on how you choose the directions of currents you may get a negative value. It does not necesarily mean that you made a mistake. Just use the magnitude (absolute value) of the current to choose your answer. 2.00 0. E1 3.00 0 Two point charges, q1 =2 #0 and q2=5 MC are placed in vacuum. Each one experiences a 5.0 N electric force due to the other charge. If each of the charges is increased by a factor of 5 the electric force on each of them becomes
