A positively charged ion travelling with charge equivalent to 1e and mass 3.17 x 10^−26 kg is accelerated in a vacuum between two parallel plates with a potential difference of 5.00 x 10^2 V between
them. The ions move into a uniform external field wirh a strength of 0.2T

a) determine the speed of the ion as it leaves the parallel plates
b) determine the magnetic force (mag and dir) experienced by the ion as it enters the magnetic field
c) determine the radius of the ion's path (in m) while it is in the uniform magnetic field
