\( \Lambda \) bob of mass \( m \) hangs by a light inextensible string which is connected with a rigid support after passing over a smooth pulley \( P \). If the bob is released from an angular position \( \theta=30^{\circ} \). then
(1) The force exerted by the string on the pulley is \( \sqrt{3} \mathrm{mg} / 2 \)
(2) The net horizontal force exerted by the string on the pulley is \( \sqrt{3} m g / 2 \)
(3) Acceleration of the bob is \( g / 2 \)
(4) The force exerted by the string on the wall is \( 2 m g / \sqrt{3} \)
