(ii) Why should the lower block of this pulley system be of negligible weight?

Expert Answer:

Efficiency gets reduced due to the weight of lower block pulleys. More the weight of lower block pulleys, less the efficiency.
Hence for greater efficiency, the pulleys in the lower block should be as light as possible.
