3. Alpha particles, charge +2e and mass 6.64 x 10-27 kg, are emitted from a radioactive source with an initial kinetic energy of 8.00 x 10-13 J. They enter a uniform magnetic field as shown in the diagram. (a) Draw the trajectory of the alpha particles in the magnetic field on the diagram. (b) Determine the magnitude of the magnetic field, B, needed to bend the alpha particles in a circular path with a radius of 0.70 m. (c) An electric field that is perpendicular to both the magnetic field and the initial velocity of the alpha is applied, and the alpha particles now move in a straight, horizontal line. Determine the electric field, both its direction and magnitude. . . . . . . . .
