A thin rope AB has a total mass m length and has its mass per unit length varies linearly from zero at end A to some maximum value at end B It is kept as a heap on a horizontal surface The end A is pulled horizontally away from the heap by applying a force F on it At any instant the length of the rope pulled out is say x Assume that the heap as such is stationary there is no friction in the rope with itself Neglecting the weight of the pulled out rope Then Q7 What is the force F to have a constant velocity of the pulled out part
