Question

4. Alpha particles of mass 6.68 x 10 kg and charge
3.2 x 10-19 C are accelerated in a cyclotron in which
a magnetic field of 1.25 T is applied perpendicular
to the dees. How rapidly should the electric field
between the dees be reversed ? What are the
velocity and kinetic energy of an alpha particle
when it moves in a circular orbit of radius 25 cm?
