The negative charged particle moving in theis subject to a magnetic force due to a constant explainmagnetic field that points in the . Assume that the electron loses 10 percent of its kinetic energy Bz Directionafter 20 turns, as a consequence of frictional forces . Calculate the fractional change in both the radius of the orbit and the angular momentum during the same 20 turns.

so easy. just google the electromagnetic waves and it’ll pop up.
