1. Two charges are placed between the plates of a parallel plate
capacitor. One charge is +q1 and the other is q2 = +4.66mC
(microC). The charge per unit area on each plate has a magnitude of

GOAL Use the superposition principle to calculate the electric
field due to two point charges. Consider the following
figure.
The resultant electric field at P equals the
vector sum 1 + 2, where 1 is the
field due to the positive charge q1and
2 is the field due to the negative charge
q2.Two point charges lie along the
x-axis in the x y-coordinate plane.
Positive charge q1 is at the origin, and
negative charge q2 is at (0.300 m, 0). Point...
