Apositive charge of 6.0 × 10-4 c is in an electric field that exerts a force of 4.5 × 10-4 n on it. what is the strength of the electric field?

The force F produced by an electric field of intensity E on a charge of magnitude q is given by

In our problem, we know the magnitude of the charge () and of the force (), so we can find the intensity of the electric field:

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.
