A proton moves in a uniform magnetic field of strength 0.500 T magnetic field is directed along the x-axis. At initial time, t= 0s, the proton has a velocity of 1.95x10^5i +2.00x10^5k m/s. Find:
a. At initial time, what is the acceleration of the proton.
b. What is the acceleration of the proton at t=3 mins.?
