Question
The six objects shown in Figure $P 14.41$ have equal-magnitude electric charge. Adjacent objects are separated by distance $a$ . Write an expression in terms of $q$ and $a$ for the force that the five objects on the right exert on the positive charge on the left.
Step 1
The direction of the force is determined by the sign of the charges. In this case, all charges are positive, so the forces are repulsive. Show more…

Four point charges are at the corners of a square of side $a$ as shown in Figure $\mathrm{P} 15.8$. Determine the magnitude and direction of the resultant electric force on $q$, with $k_{e}, q$, and $a$ left in symbolic form.
In the figure, a third point charge $-q$ is placed at point $P$ What is the electric force on $-q$ due to the other two point charges?
