1. The problem statement, all variables and given/known data A smooth bead B is threaded on a light inextensible string. The ends of the string are attached to two fixed points A and C on the same horizontal level. The bead is held in equilibrium by horizontal force of magnitude 2N acting parallel to CA. The section of the string make angles of 60 and 30 with the horizontal. Find the tension in the string. 2. Relevant equations Resolve the tension into X and Y component and then use F=Ma to solve it. 3. The attempt at a solution Question 1) From the answer book, it says that the tension in the both string are same. Is it due to the word inextensible. Question 2) there is more than one way to approach this question, I tried to use Alternating angle as CA is parallel to 2N . Then Cos60=2/H and make the H the subject, I got 4 newtons, but this answer is wrong. Can someone please tell me if I had made any wrong assumption. Thank you in advance.
