Exercise 7

Negative charge between two equal charges

Theory used: Superposition principle Charges on a line

On the $x$ -axis, in vacuum, there are the point charges $q_{1} = + 5.0 μ C$ at $x = 0$ and $q_{2} = + 5.0 μ C$ at $x = 0.40 m$ . Compute the magnitude and orientation of the total force on the charge $q_{0} = - 1.0 μ C$ placed at $x = 0.10 m$ .
