Write an expression for the force exerted on a charge q which is moving at velocity v by: 1. An electric field E⃗ 2. A magnetic field B⃗ 3. If an electric field and a magnetic field are both present, would a force be exerted on the charge even if the charge were initially not moving? Explain your reasoning

It won't lose or gain electrons if it's a covalent bond it shares the electrons with another atom or atoms. if it is an ionic bond it will lose the 3 electrons on the outer shell and become a positively charged ion.  credit goes to @sunshinebaby of answers.yahoo.com.

Answerthe force between the charges will be  f/9 (one-ninth of force f)explanationcoulomb's law relates the magnitudes  two point charges q₁ and q₂, the distance, r, between the charges, and the electrostatic force, f, between the two charges:     k represents coulomb's constant, k = 8.99×10⁹ n·m²/c².note that if we have r = 3r, then   

Iwould think it is temperature, silica, oxides (gases)
