A rope of mass is connected at the same height of two opposite walls. It is allowed to hang under its own weight. At [he contact point between the rope and the wall, the rope makes an angle with respect to horizontal. The tension in the rope at its midpoint between the walls is
1
2.78 N
2
2.56 N
3
2.82 N
4
2.71 N
Official Solution
Correct Option:
(3)
Let the tension in each section and be . Now, from the condition of equilibrium it is clear that the horizontal components are equal in magnitude and opposite to each other so they cancel out each other. Hence,
