18A simple pendulum of mass \( m \) executes SHM with total energy \( E \). If at an instant it is at one of extreme positions, then its linear momentum after
\( \mathrm{P} \)
W
a phase shift of \( \frac{\pi}{3} \) rad will be
(1) \( \sqrt{2 m E} \)
(2) \( \sqrt{\frac{3 m E}{2}} \)
(3) \( 2 \sqrt{m E} \)
(4) \( \sqrt{\frac{2 m E}{3}} \)
