Question

a ball weighing 100 n is shown suspended from a system of cords. what is the tension in the horizontal and angled cords at 50 degrees and 90 degrees

Answer 1

First, we know that the ball is not in motion, so the acceleration is 0

T45 = Fg/sin45 = 100N/sin 45 = 141 N

Thor = T45 cos 45 = 141 N cos45

= 100 N

hope this helps
