A proton is passing through a uniform, 0.500-T magnetic field and is directed along the x axis. At t=0 the proton has the velocity components v(x)= 1.5x10^5 m/s and v(y)= 2.00x10^5 m/s. Only the magnetic fields act on the proton.
a. find the force on the proton.
b. find its acceleration at t=0.
c. find the radius of the resulting helical path.
d. find the angular speed of the proton.
e. find the pitch of the helix.
