Answer:
1.Charged particles in motion are deflected by electric and magnetic fields, and their behavior is described either by the Lorentz equation, which is Newton's equation of motion modified to include any relativistic effects, or by Schrödinger's equation when spin is negligible.
2.imbalance of electric charges within or on the surface of a material.
3.Coulomb's law equation for electrical force bears a strong resemblance to Newton's equation for universal gravitation. The two equations have a very similar form. Both equations show an inverse square relationship between force and separation distance.
C. the current of a charged object: d. the distance between charged objects
A. mass of a charged object: b. # of excess electrons on the object
