Gce Model Questions Vol1 2022 Physics Question 35
Practice objective / multiple choice question 35 from the 2022 Gce Model Questions Vol1 Physics examination.
A 10 kg block is lifted vertically by a rope‑pulley system consisting of two fixed pulleys and one movable pulley attached to the block. The rope passes over the first fixed pulley, under the movable pulley, and over the second fixed pulley to the hand. The system is ideal except that the movable pulley exerts a resisting force equivalent to 5 N due to friction. The block is raised at constant speed. Determine the magnitude of the constant force that must be applied to the free end of the rope (the hand force) in newtons.
