A bar supporting a bloCk on its top is placed on a frictionless plank that rests on a horizontal floor. The bar is attached to a nail driven into the lenk with the help of a spring as shown in the figure. Coefficient of ietion between the bar and the block is u. What maximum acceleration parallel to the spring can the plank be given preventing sliding between he block and the bar? Acceleration due to gravity is g.
