A trolley A has a simple pendulum suspended from a frame fixed to its deck . A block B is in contact on its vertical side . The trolley is on horizontal rails and accelerate towards the right ,such that the block id just prevented from falling. if the value of coefficient of friction between A and B is 0.5,find the value of the inclination of the pendulum to the vertical.
