A small sphere with mass \(m\) and positive charge \(q_1\) is suspended from a ceiling by a light insulating thread. A second small sphere with positive charge \(q_2\) is fixed directly below the suspended sphere at a distance \(d\). The gravitational force acting on the suspended sphere is \(0.50 \text{ N}\), and the electrostatic repulsive force between the two spheres initially has a magnitude of \(0.20 \text{ N}\). If the fixed sphere is moved downward so that the distance between the two spheres is doubled to \(2d\), what is the new tension in the thread?
