Point charges 91 +12 nC and q2 = - 12 nC are 0.100 m apart. (Such pairs of point charges with equal magnitude and opposite sign are called electric dipoles.) Compute the electric field caused by q, the field caused by q2, and the total field (a) at point a; (b) at point b; and (c) at point c. 13.0 cm 13.0 cm 42

Two charges, q1=-0.3mC and q2=--1.94mC are placed 12.02m apart from one another (mC stand for "milli-Coulomb").  What is the the electric force that q2 experiences due to the presence of q1?  Note, if the force direction is "to the left" be sure to include a negative sign.  If the direction of the force is "to the right", the force should be positive in sign.

Consider the symmetrically arranged charges in the figure, in which qa= b = -3.65 µC and qe = qd = +3.65 μC. Determine the direction of the electric field at the location of charge q. down and left up and left down and right E = Oleft down up and right up right Calculate the magnitude of the electric field E at the location of a given that the square is 5.45 cm on a side.
