An electron ( charge = -1.6 e^-19 C ) is moving at 3.0 e + 5 m/s in the positive X direction. A magnetic field of 0.8 T is in the positive Z direction. Find the magnetic force on the electron. Hint: use -q instead of +q in the magnetic force equation and remember force is a vector.
An iron disk has a radius of 0.445 m and a mass of 367 kg. The disk is mounted on its axis so that it is free to spin. If the torque is applied at the edge of the disk, how much force is required
For the situation, the magnetic field changes with time according to the expression B = (2.00t3 - 4.00t2 + 0.800)T, and r2 = 2R = 5.00 cm. (a) Calculate the magnitude and direction of the force exerted on an electron located at point P2 when t = 2.00..
