Question

Two charges of `3 C` and `2 C` are positioned on a line at points `6` and `4`, respectively. What is the net force on a charge of `3 C` at `2`?

Answer 1

HINT:

The electrostatic force `F` between two point charges `Q_1` & `Q_2` separated by a distance `D` is given by the following formula

`F=\frac{1}{4\pi\epsilon_o}\frac{Q_1Q_2}{D^2}`
