If an object has more protons than electrons, then the net charge on the object is positive. If there are more electrons than protons, then the net charge on the object is negative. If there are equal numbers of protons and electrons, then the object is electrically neutral.

Hope this helps :)
Since the direction of the force and the direction of the path is perpendicular, the person is not doing any physical work.
KE = 1/ 2 * 1252 * 144
as KE = 1/2 * m * v ^2
= 90144 J
You know I’m going to be honest I don’t feel like it
