Homework Statement
A block is suspended from two ropes so that it hangs motionless in the air. If the magnitude of T2 is 10N, what is the magnitude of T1? Here is the figure given: See attachment
Choices:
.5N
.866N
10N
17.3N
Homework Equations
My teacher told me to use trig functions so I need to use cosine.
The Attempt at a Solution
First I have to find the adjacent side for T2. I know the hypo is 10N.
Cos(60)= adj/10N
.5= adj/10N
.5 times 10N= 5
5 is the adjacent
Then using that... I have to find the hypo of T1. I know the adjacent is 5.
Cos(30)= 5/hypo
.866=5/hypo
.866 times 5= 4.33
What did I do wrong?
