Please ,
Explain me this situation
A spider is attached to two threads of equal length that make a 120o angle with each other. The spider is motionless and its mass is m=30mg.
What is the tension in each thread?
According to the Newton first Law, the sum of the force must be 0.
T1+T2+Fspider=0
since the threads are the same length and symetrical, T1=T2.
Fspider=-3.0 *10-4N
so I found T1=1.5 *10-4N
I am surprised to see that the answer is 3.0 *10-4N on each thread
please now I am confused! help
