(1 )An alpha particle (q = +2e, m = 4.00 u) travels in a circular path of radius 6.62 cm in a uniform magnetic field with B = 1.19 T. Calculate (a) its speed, (b) its period of revolution, (c) its kinetic energy, and (d) the potential difference through which it would have to be accelerated to achieve this energy.

2) A proton travels through uniform magnetic and electric fields. The magnetic field is in the negative x direction and has a magnitude of 2.44 mT. At one instant the velocity of the proton is in the positive y direction and has a magnitude of 2350 m/s. At that instant, what is the magnitude of the net force acting on the proton if the electric field is (a) in the positive z direction and has a magnitude of 4.31 V/m, (b) in the negative z direction and has a magnitude of 4.31 V/m, and (c) in the positive x direction and has a magnitude of 4.31 V/m?
