2 131 A thin rod AB of length 3m is pivoted at A so that it can rotate freely about A in a vertical plane Its linear density of mass 2 varies as Kx where K kg m and x is the distance from the end A When the rod is in equilibrium a sharp impulse of 27 N s is given to it at the end B in horizontal direction in the 416 plane of rotation If the force exerted on the rod by the pivot when it becomes horizontal is Newton n then find the value of n A
