A proton (q = 1.60×10?19C , m = 1.67×10?27kg)moves in a uniform magnetic fieldB? =( 0.490T )i^. At t = 0 the proton has a velocity components vx = 1.50×105m/s , vy=0, and vz = 2.30×105m/s .
A. What is the magnitude of the magnetic force acting on the proton?
B. What is the direction of the magnetic force acting on the proton?
