I'm working on the following question:(adsbygoogle = window.adsbygoogle || []).push({});

"A painting of mass 3.20 kg hangs on a wall. Two thin pieces of wire, each 0.250 m long, connect the painting's center to two hooks in the wall. The hooks are at the same height and are 0.330 m apart. When the painting hangs straight on the wall, how much tension is in each piece of wire? (It is assumed that the wire is massless)"

I found the angle between one of the angles and the horizontal line connected the two hooks (48.7 degrees). Then, I used the weight (mg = 31.36) and the angle to calculate the tension in the rope (41.7 N).

I know that the answer is half of that, but at what point should I divide by two in order to find the tension in each piece? My guess is that I divide the final answer by two. I guess I'm unsure of whether tension is the same throughout the whole wire.
