A light string ABCDE whose midpoint is C passes through smooth rings B and D, which are fixed in a horizontal plane distant 2a apart. To each of the points A,C,E is attached a mass m. Initially C is held at rest at O(midpoint BD) and is then set free. What is the distance OC when C comes to instantaneous rest.
let answer be 'h'. BC=DC=√(a^2 +h^2)-a, therefore masses at A and E rise by this amount. from conservation of energy, 2mg(√(a^2 +h^2)-a)=mgh,upon solving this equation we get h=4a/3
