A mass of \( 10 \mathrm{~kg} \) is suspended by a rope of length \( 2.8 \mathrm{~m} \)
\( \mathrm{P} \) from a ceiling. A force of \( 98 \mathrm{~N} \) is applied at the

W midpoint of the rope as shown in figure. The angle which the rope makes with the vertical in equilibrium is
(1) \( 30^{\circ} \)
(2) \( 60^{\circ} \)
(3) \( 45^{\circ} \)
(4) \( 90^{\circ} \)
