Document Summary
Physics 232 : formula sheet for midterm 2: coulomb"s law : R12 = q2 ~e12 , where ~f , ke, q1, q2, ~r12 are the force, ke = 1. 4 0 the free space, charges q1 and q2, and the vector from the charge q1 to q2. ~e12 is the electric eld due to the charge q1 to the position of the charge q2. with the 0 = 8. 85 10 12 c 2: electric eld ~e : = i ~e d ~a = 0 where , d ~a, qin are the electric ux, area vector (with direction outward normal to the surface), and the net charge enclosed in the gaussian surface: electric potential v and eld ~e: V (b) v (a) = z b. K , where a, b are two di erent locations that are connected by a path through the in nitesimal vector ~s. Electric potential v can be also directly evaluated for the continuous charge distribution.
