Three point charges are in a straight line. Their charges are \(Q_{1}=+4 \times 10^{-9} \mathrm{C}, Q_{2}=+2 \times 10^{-9} \mathrm{C}\) and \(Q_{3}=-6 \times 10^{-9} \mathrm{C}\). In the diagram below, point charge \(A\) has a charge of \(+16 \mu C . X\) is a point \(12 \mathrm{~cm}\) from point charge \(\mathrm{A}\).

Two positive point charges, \(q_{1}=+16 \times 10^{-6} \mathrm{C}\) and \(\mathrm{q}_{2}=+4 \times 10^{-6} \mathrm{C}\), are separated by a distance \(3 \mathrm{~m}\). Two point charges, \(Q_{1}\) and \(Q_{2}\), a distance \(3 \mathrm{~m}\) apart, are shown below. The charge on \(Q_{1}\) is \(-14 \mu \mathrm{C}\) and the charge on \(Q_{2}\) is \(+20 \mu \mathrm{C}\)

Below is a diagram of a charged object (conductor) at electrostatic equilibrium. Points \(A, B\), and \(D\) are on the surface of the object, whereas point \(\mathrm{C}\) is located inside the object. In each of the four scenarios listed below, the two charges remain fixed in place as shown. Rank the forces acting between the two charges from the greatest to the least. In each of the four scenarios listed below, the two charges remain fixed in place as shown. Rank the electric potential energies of the four systems from the greatest to the least.
