SUMMARY
The tension in the cables suspending a 20kg loudspeaker, positioned 2m below the ceiling with two 3m long cables angled outward, is calculated to be 147N. The weight of the loudspeaker is determined using the equation w=mg, yielding a weight of 196N. To find the tension, it is essential to analyze the forces acting on the loudspeaker by breaking them down into components, considering that both cables experience equal tension due to their symmetrical arrangement.
