Question: A rope with two mass-less platforms at its two ends passes over a fixed pulley, as shown in the figure. Discs with narrow slots and an equal weight of 20 N each can be placed on the platforms. The number of discs placed on the left-side platform is n, and that on the right-side platform is m. It is found that for n = 5 and m = 0, a force F= 200 N (refer to part (i) of the figure) is sufficient to initiate upward movement of the left side platform. If the force F is removed, Find the minimum value of m (refer to part (ii) of the figure) required to prevent the downward motion of the left side platform.
