Igcse Model Questions Vol1 2019 Physics Question 2
Practice objective / multiple choice question 2 from the 2019 Igcse Model Questions Vol1 Physics examination.
A block of mass \(30\ \text{kg}\) is lifted at constant speed by a simple block‑and‑tackle consisting of a fixed pulley and a single movable pulley. The rope passes over the fixed pulley, then under the movable pulley attached to the block, and the free end is pulled vertically upward. Because of friction in the fixed pulley, the tension in the rope segment supporting the block is \(4\%\) less than the tension in the segment where the effort is applied. What magnitude of effort force (in newtons) must be applied to raise the block?
