WebbThe magnitude of the force of +Q or -Q on q o at r = 3 m is F qQ = kQq o /r 2 = (9.0 x 10 9 N-m 2 /C 2 ) (2 x 10 -6 C) (10 -12 C)/ (9 m 2) = 2 x 10 -9 N. The force of +Q on +q 0 at P 1 is to the right since +Q repels +q o and urges it to the right P 2 is to the left since +Q repels +q o and urges it to the left. The force of -Q on + q o at WebbV = kQ r ( Point Charge). 19.38. The potential at infinity is chosen to be zero. Thus V for a point charge decreases with distance, whereas E for a point charge decreases with distance squared: E = F q = kQ r 2. 19.39. Recall that the electric potential V is a scalar and has no direction, whereas the electric field E is a vector.
WebbCombining the two equations, you get coulomb's law, F = E q = k Q r 2 q Regarding the parallel plates, we make use of electric field beause its simply far easier to deal with. In fact, the electric field which exists between two parallel plates is produced by the many charges which exist on the plates.
