3. The vector quantity that measures the strength of a dipole.
6. The force between two like charges.
8. The SI unit of electric flux (use letters and symbols, no spaces).
9. Charging a body without touching it, by bringing it near a charged body.
10. The law relating electric flux through a closed surface to the enclosed charge.
11. The direction of electric field lines from a positive charge.
