Two metallic rods of length 40 cm and unknown linear mass density are suspended from a support using lightweight strings of length 8 cm.
The rods are then connected to a circuit in such a way that same current 20 A passes through both rods, but flows in opposite directions. When connected in such a way, the rods move away from each other and at equilibrium are separated by a distance 2 cm. What is the linear mass density of the rods?

Two parallel long (infinite for our purposes) wires are suspended by a system of thin strings of length L=3.2 cm each as illustrated in the figure below showing the plane perpendicular to the wires. These wires are part of the electric circuit and run the same (but unknown) current I in the opposite directions. We treat the current I algebraically assigning the positive values to the current running out of the screen towards us (hence, currents I and −I next...

Two small metallic spheres, each with a mass of m = 9.00 g, are suspended from a common point by two strings of negligible mass of length L = 27.0 cm. When the spheres have an equal amount of charge, the two strings make an angle of 60° with each other as shown in the figure below. Calculate the magnitude of the charge on each sphere.
Two small metallic spheres, each of mass m = 0.45 g, are suspended as pendulums by light strings from a common point. The spheres are given the same electric charge, and it is found that they come to equilibrium when each string is at an angle of θ = 3.3° with the vertical. If each string has length L = 36.0 cm, what is the magnitude of the charge on each sphere?
