A massless string \( \mathrm{AB} \) is loaded at its centre \( \mathrm{O} \) by
\( \mathrm{P} \)
mass \( m \). If its ends \( A \) and \( B \) are on the same
W
horizontal line, then tension in the strings \( \mathrm{OA} \) is
(1) \( \frac{m g}{2} \)
(2) \( m g \)
(3) \( \frac{\sqrt{3} m g}{2} \)
(4) \( \frac{m g}{\sqrt{3}} \)
