A body is hanging from a rigid support by an inextensible string of length \( l \) . It is struck inelastically by an identical body of mass \( m \) with horizontal velocity \( v=\sqrt{2 g l} \), the tension in the string increases just after the striking by
(1) \( m g \)
(2) \( 3 \mathrm{mg} \)
(3) \( 2 \mathrm{mg} \)
(4) none of these
