INTIALLY ITS AT EQUI

now its slightly disturbed .. let it move by a small angle A (:P)

kb^2 A = mc^2(W^2 A)

âˆškb^2/mc^2 = W

ASSUMPTION ==> ROD IS MASSLESS!!!!!!!!!!!

vaishnavi is the mass M fixed or moving?????????????

yup it is given tat all the surfaces r smooth so M must move rit???

m sry i forgotten to mention..
