look the force acting on particle is F= dmv^2 / r ----1
now for finding velocity use energy conservation ..
potential energy at 60 degress = P.E. at 37 + Rotational energy at 37
dmgL - dmglcos60 = dmgl - dmglcos37 + 1/2 I  ^2
dmgl(1-cos60) = dmgl(1-cos37) + 1/2 I  ^2
now write = v/r
and solve for v
and put value in 1 to get ans...
