Q1. Three long wires (wire 1, wire 2, and wire 3) hang vertically. The distance between wire 1 and wire 2 is 20.0 cm. On the left, wire 1 carries an upward current of 1.20 A. To the right, wire 2 carries a downward current of 4.80 A. Wire 3 is situated such that when it carries a certain current, each wire experiences no net force. Find out:

(a) position of wire 3

(b) magnitude and direction of the current in wire 3

Q2. A loudspeaker of mass 22.0 {rm kg} is suspended a distance of h = 1.60 {rm m} below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of l = 3.90 {rm m}.

What is the tension T in each of the cables?

Use 9.80 {rm m/s}^2 for the magnitude of an acceleration due to gravity.
