21.96 Two charges are placed as
Figure P21.96
shown in Fig. P21.96. The magnitude
al
of q is 3.00 uC, but its sign and the
12.0 cm
5.0 cm
value of the charge q2 are not known.
The direction of the net electric field
E at point P is entirely in the negative
y-direction. (a) Considering the different
possible signs of q and q2, four possible diagrams could represent the electric
fields E and E produced by q and q2. Sketch the four possible electric-
field configurations. (b) Using the sketches from part (a) and the direction of
E, deduce the signs of q and q2. (c) Determine the magnitude of E.
