a proton and a alpha particle enter a uniform magnetic field with same velocity find the time period of rotation of alpha particle

Asked by akshay | 2nd Sep, 2012, 10:22: PM

Expert Answer:

the time period is expressed as:
 
T=(2?m)/(qB)
 
thus for the given particles:
for proton:
T1 = (2?m)/(qB)
 
for alpha particle:
T2 = (2?4m)/(2qB)
 
thus clearly:
 
T2 = 2 x T1
