An electron is located in an electric field of magnitude 7A. 3.00 × 10 –9-coulomb test charge is placed near a 1.67 × 10-3 newtons per coulomb. What is the magnitude of the electrostatic force acting on the electron?

Kinetic energy = 1/2mv^2. since the mass is constant we can form a ratio of it's kinetic energy at 60 divided by that at 30 to see ke(60)/ke(30) = +(60^2)/30^2). this may be said to 300% increase.

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.
