One end of a rope is fixed to a vertical wall and
\( \mathrm{P} \) the other end is pulled by a horizontal force of \( 20 \mathrm{~N} \).

W
The shape of the flexible rope is shown in figure.
The mass of the rope is-
(1) \( 2 \mathrm{~kg} \)
(2) \( 3 \mathrm{~kg} \)
(3) \( 3.5 \mathrm{~kg} \)
(4) \( 4.5 \mathrm{~kg} \)
