At a particular instant a proton is traveling in the −x direction, with speed 5 × 105 m/s. At the location of the proton there is

a magnetic field of magnitude 0.24 T in the −y direction, due to current running in a nearby coil. What are the direction

and magnitude of the magnetic force on the proton?
