1.	A block of mass M is pulled along a horizontal frictionless surface by a rope of mass m. Force F is applied at one end of the rope. Find the force which the rope exerts on the block.
Answer» Solution :ACCELERATION in (block + rope) SYSTEM i.e., `F=(M+m)a=Ma+ma` The force with which the rope exerts on the black is `P=Ma=M.(F)/((M+m))`
