A proton moving in the positive x direction with a speed of 9.4 105 m/s experiences zero magnetic force. When it moves in the positive y direction it experiences a force of 2.5 10-13 N that points in the positive z direction. Determine the magnitude and direction of the magnetic field.

Biased means unfair but that's all ik

Your answer is c. explanation: plasma  is the fourth state of matter, derived from the gaseous state of matter.  plasma  can contain free  electrons  and/or  ions. while  plasma is never neutral, it can either be positively or negatively charged.  gases, however, are electrically neutral.
