WebThe greater the rate of ionisation, the shorter the path length Wrong Track: If beta particles travel farther in air, their rate of ionisation of air molecules must be greater than for alpha particles. Right Lines: If beta particles travel farther in air, their rate of ionisation of air molecules must be less than for alpha particles. WebThe time for the charged particle to go around the circular path is defined as the period, which is the same as the distance traveled (the circumference) divided by the speed. Based on this and Equation 11.4, we can derive the period of motion as. T = 2 π r v = 2 π v m v q B = 2 π m q B. 11.6.
