The arrangement shown in the figure is a pulley system, with a mass (M) attached to one end and a counterweight (m) attached to the other end.
The acceleration of M can be calculated using the formula a = (m - M)g / (m + M), where g is the acceleration due to gravity.
The counterweight is used to balance the system and ensure that the acceleration of M is solely due to the force of gravity pulling on it.
The acceleration of M is inversely proportional to the mass of the counterweight. This means that as the mass of the counterweight increases, the acceleration of M decreases.
No, this arrangement is a simplified model for understanding the concept of pulleys. In real life, there are other factors such as friction and the weight of the pulley itself that can affect the acceleration of M.
