1. The problem statement, all variables and given/known data
One end of a rope is fixed to a vertical wall and the other end pulled by a horizontal force of 20N. The shape of the flexible rope is shown in the figure. Find its mass.
2. Relevant equations
3. The attempt at a solution
Let the wall exert a force F in the tangential direction at the point where rope is fixed. Let the tangent make an angle θ with vertical.
Fcosθ=mg
Fsinθ=20
cotθ= mg/20
But θ is still unknown! :confused:
