A simple pendulum with a bob of mass ' \( m \) ' oscillates from \( A \) to \( C \) and back to \( A \) such that \( P B \) is \( H \). If the acceleration due
\( \mathrm{P} \) to gravity is ' \( g \) ', then the velocity of the bob as it passes

W through \( B \) is [CBSE PMT 1995; DPMT 1995; Pb. PMT 1996;
(a) \( m g H \)
(b) \( \sqrt{2 g H} \)
(c) \( 2 g H \)
