Question
Positive point charges $q$ and $2 q$ are located at $x=0$ and $x=3 d,$ respectively.What is the electric field at $x=2 d$ (point $S$ )?
Step 1
The electric field due to a point charge is given by the formula $E = k \frac{q}{r^2}$, where $k$ is Coulomb's constant, $q$ is the charge, and $r$ is the distance from the charge. Show more…

Positive point charges $q$ and $2 q$ are located at $x=0$ and $x=3 d,$ respectively. What is the electric field at $x=d$ (point $P$ )?
2. Three charges equal to -Q, +Q and +Q are located a distance a apart along the x axis (see figure 1). The point P is located on the positive y-axis a distance a from the origin. (a) What is the electric field E at point P? (10)
Three charges are on the $y$ -axis. Two of the charges, each $-q$, are located $y=\pm d$, and the third charge, $+2 q$, is located at $y=0$. Derive an expression for the electric field at a point $P$ on the $x$ -axis.
