A stationary particle of charge q = 1.4 10-8 C is placed in a laser beam (an electromagnetic wave) whose intensity is 3.5 103 W/m2. Determine the magnitudes of the (a) electric and (b) magnetic forces exerted on the charge. If the charge is moving at a speed of 3.7 104 m/s perpendicular to the magnetic field of the electromagnetic wave, find the magnitudes of the (c) electric and (d) magnetic forces exerted on the particle.
Don't you have standard force equations for moving particles in magnetic fields, and charges in E fields to do this?
