A proton (q=1.60*10^-19C, m=1.67*10^-27kg) moves in a uniform magnetic feild B=(0.500T)i. At t=0 the proton has velocity components vx=1.50*10^5 m/s, vy=0 and vz=2.00*10^5m/s.
a) what are the magnatidue and direction of the magnetic force acting on the proton? in addition to the magnetic field there is a uniform electric firld in the x-direction, E=(+2.00*10^4 V/m)i.
b) Will the proton have a component of acceleration in the direction of the electric field?
c) Describe the path of the proton. Does the electric field affect the radius of the helix? explain.
d) at t=T/2, where T is the period of the circular motion of the proton, what is the x-component of the displacement of the proton from its postions at t=0?
