A rope of mass \( 0.1 \mathrm{~kg} \) is connected at the same height of two
\( \mathrm{P} \) opposite walls. It is allowed to hang under its own weight. At

W the contact point between the rope and the wall, the rope makes an angle \( \theta=10^{\circ} \) with respect to horizontal. The tension in the rope at its midpoint between the wall is
