Q)
(chatquestion)...electron's acceleration.
2 A wire of length 0.655 m carries a current of 21.0 A. In the presence of a 0.470-T magnetic field, the wire experiences a force
of 5.46 N. What is the angle (less than 90°) between the wire and the magnetic field?
3 The resistance per unit length of a piece of copper wire is 5.90 x 10 0/m. The wire is wound into a thin, flat coil of many turns
that has a radius of 0.140 m. The ends of the wire are connected to a 12.0-V battery. Find the magnetic field strength at the
center of the coil.
4. Two parallel wires 200 mm apart carry currents in the same direction of 5.0 A. Find the magnetic field between the wires, 50
mm from one of them and 150 mm from the other.
5. A charge of +1.0 x 10 C is moving at 500 m/s along a path parallel to a long, straight wire and 100 mm from it. The wire
carries a current of 2.0 A in the same direction as that of the charge. What is the magnitude and direction of the force on the
charge?...(3,4,5.. Anyone)
