# Thread: charged objects in a vacuum

1. ## charged objects in a vacuum

In a vacuum, two particles have charges of q1 and q2, where q1 = +3.07 mC. They are separated by a distance of 0.206 m, and particle 1 experiences an attractive force of 3.60 N. What is the magnitude of q2?

Again,
$F = \frac{kq_1q_2}{r^2}$
