An alpha particle (a He nucleus, containing two protons and two neutrons and having a mass of 6.641027 kg) traveling horizontally at 35.6 km/s enters a uniform, vertical, 1.10 T magnetic field. 
A) What is the diameter of the path followed by this alpha particle? 
B) What effect does the magnetic field have on the speed of the particle? 
C) What are the magnitude of the acceleration of the alpha particle while it is in the magnetic field? 
D) What are the direction of the acceleration of the alpha particle while it is in the magnetic field?

(a) qVB=mV2R
R=mVqB
R=6.64102735.610321.610191.1=6.72104
The diameter (D)=2R=13.44104 m


b) While the magnetic field does not affect speed, it does force a particle to proceed in a circular path.


c) (a)=V2R=(35.6103)26.72104=1.891012ms2


d) The acceleration will go in the direction of the center.
