8. You want to lift a heavy block through a heighth by attaching a string of negligible mass to it and pulling so that it moves at a constant velocity You have the choice of lifting it either by pulling the string vertically upward or along a frictionless inclined plane (see Figure). Which one of the following statements isjnre? l l If as; a m\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ :1, (I) (if) (a) The magnitude of the tension force in the string is smaller in case (i) than in case (ii). (b) The magnitude of the tension force in the string is the same in both cases. (c) The work done on the block by the tension force is the same in both cases. (d) The work done on the block by the tension force is smaller in case (ii) than in case (i) (e) The work done on the block by the gravitational force is smaller in case (ii) than in case (i)
