Agree
When two blocks of equal mass are attached to the two ends of a light string and one of the blocks is placed over a smooth horizontal plane while the other is hung freely after passing over a smooth pulley, then the two blocks will have some motion. This is because of the following reasons:
1. Force of gravity: Both the blocks have the same mass and are subject to the same force of gravity, which pulls them downwards.
2. Tension in the string: As the block on the right-hand side is hung freely, it exerts a force on the string, creating tension in the string.
3. Inertia: The block on the left-hand side, which is placed over a smooth horizontal plane, has inertia and resists the motion created by tension in the string.
4. Newton's Second Law: According to Newton's Second Law, the acceleration of an object is directly proportional to the force applied to it. As the block on the right-hand side exerts a force on the string, the block on the left-hand side experiences an acceleration in the direction of the string.
5. Conservation of energy: The potential energy of the block on the right-hand side is converted into kinetic energy as it moves downwards, which is then transferred to the block on the left-hand side, making it move.
Therefore, it can be concluded that the two blocks will have some motion when they are attached to the two ends of a light string and one of the blocks is placed over a smooth horizontal plane while the other is hung freely after passing over a smooth pulley.
