Expert Solution

Step 1

To plot the electric field lines due to the charges and to plot the force on charge $q_{3}$ .

Given:
Charge of $q_{1}$ : $q_{1} = 1 C$
Charge of $q_{2}$ : $q_{2} = q_{1} = 1 C$
Charge of $q_{3}$ : $q_{3} = - 2 C$
Position of $q_{1}$ : $r_{1} = (- 3, 0)$
Position of $q_{2}$ : $r_{2} = (1, 0)$
Position of $q_{3}$ : $r_{3} = (0, 0)$

To find:
The net field at point P: $\vec{E_{n e t}}$
The force on $q_{3}$ : $F$

According to Coulomb's law, the force between two charged objects is given by:
$F = \frac{k q Q}{r^{2}}$
where,
$q$ and $Q$ are the two charges,
$r$ is the distance between the two charges and
$k$ is the Coulomb constant. The value is: $k = 9 \times 10^{9} {N.m}^{2} {/C}^{2}$
