Question

Reproduce$FIGUREQ25.12$on your paper. Then draw a dot (or dots) on the figure to show the position (or positions) at which the electric potential is zero.

Short answer

The reproducing diagram is

Step-by-step solution

Step: 1 Finding the value for diagram:

Position of two charges at potential is

$U\left(x\right)=\frac{2q}{4\pi {ϵ}_0\left|x\right|}+\frac{(-q)}{4\pi {ϵ}_0|x-3|}$

Where localid="1648820269317" $x=0$in localid="1648820266806" $2q$charge and localid="1648820252518" $x=3$in localid="1648820260629" $-q$charge.

Step: 2 Finding value and reproducing diagram:

Substituting $U\left(x\right)=0$and the value of $x$is obtained and the diagram is
