The weights B in the pulley systems shown are identical and are being lifted at the same constant speed υ. Assume there are no energy losses in the pulleys. Is the power developed by force F1 in (a) smaller than, equal to, or greater than that developed by force F2 in (b)?

Note:Concept problems are about explanations, not computations.
