Protons have _electric charge. Electrons have
_electric charge. Neutrons have
electric charge. Most atoms are electrically
because the number of protons
equals the number of electrons. Atoms with an electric charge become charged by gaining or losing
When this charge becomes built up on an object, we call that build up

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)

Three point charges have equal magnitudes, two being positive and one negative. these charges are fixed to the corners of an equilateral triangle, as the drawing shows. the magnitude of each of the charges is 5.6 µc, and the lengths of the sides of the triangle are 3.9 cm. calculate the magnitude of the net force that each charge experiences.

This scalar quantity is defined as the ability to do work
