I need help with this problem. I think I know how to do it, but I am having difficulty drawing a diagram, which is required in my class: A street lamp weighs 150 N. It is supported by two wires that form an angle of 120.0° with each other. The tension in the wires are equal.
a) what is the tension in each wire supporting the street lamp?
b) If the angle between the wires supporting the street lamp is reduced to 90.0° , what is the tension in each wire?
