Determine the net force on the middle charge (2.0 x 10⁻⁶ C) given three charges and their distances.

Let's find the net force on the $2.0 \times 10^{-6}$ C charge. We will use Coulomb's Law and the principle of superposition.

The charges are:
$q_1 = 8.0 \times 10^{-6}$ C (left charge)
$q_2 = 2.0 \times 10^{-6}$ C (middle charge, the charge on which we find the net force)
$q_3 = -5.0 \times 10^{-6}$ C (right charge, as stated in the problem text)

The distances are:
$r_{12} = 2.0$ m (distance between $q_1$ and $q_2$)
$r
