When at rest a proton experiences a net electromagnetic, Ask an Expert

Academics

When at rest, a proton experiences a net electromagnetic force that has a magnitude of 7.2 x 10^-4 N and points in the positive x-direction. When the same proton later moves with a speed of 2.0 x 10^6 m/s in the positive y-direction, the net electromagnetic force decreases to a magnitude of 5.6 x 10^-14 N but still points in the positive x-direction.

i) Find the magnitude and direction of the electric field.

ii) Find the magnitude and direction of the magnetic field.
