Question


3.Two insulated wires, each 3.00 m long, are taped together to form a two-wire unit that is 3.00 m long. One wire carries a current of 7.00 A; the other carries a smaller current I in the opposite direction. The two wire unit is placed at an angle of 67.0

magnitude N direction ---Select---northsoutheastwest

An ?-particle has a charge of +2e and a mass of 6.64 times10-27 kg. It is accelerated from rest through a potential difference that has a value of 1.28 times10 6 V and then enters a uniform magnetic field whose magnitude is 2.60 T. The ?-particle moves perpendicular to the magnetic field at all times.

Explanation / Answer

1)

The force acting on the particle:
F = q*v
