... If you prefer to use the vector cross product FB = qv × B then the cross product yields both the magnitude and direction of the force on a positive charge moving in the magnetic field. If the charge is negative, the magnitude of the force will be the same, but the direction will be opposite that det ...

... that charge. The closer he brings it, the more electrical potential energy it has. When he releases the charge, work gets done on the charge which changes its energy from electrical potential energy to kinetic energy. Every time he brings the charge back, he does work on the charge. If he brought th ...

... energy and of the direction in which the electron moves (again, this follows from the mentioned laws of conservation of energy and momentum). As a result, an incident electron follows a random erratic path as it slows down in matter. This is the main difference between interaction of fast electrons ...

Physics 227: Lecture 8 Dielectrics, and Capacitors
... With the voltage V fixed, and U = ½CV2, the energy stored is proportional to C. The force between the plates is in the direction to reduce the potential energy, so the force would increase d - it is repulsive! Does this make sense considering the energy stored in the electric field? With constant V ...
