A uniform rigid lever AB of total length 2.0 m is used as a first‑class lever. A load of 300 N is attached at end B. An effort force is applied at end A. The fulcrum C is placed somewhere between A and B such that when the lever is raised, the effort end moves twice the vertical distance moved by the load end. Determine (a) the magnitude of the effort force (in newtons), and (b) the distances \(AC\) and \(CB\) (in metres).

Answer Options

A. Effort = 180 N; AC = 1.00 m, CB = 1.00 m
B. Effort = 120 N; AC = 1.50 m, CB = 0.50 m
Correct Answer C. Effort = 150 N; AC = 1.33 m, CB = 0.67 m
D. Effort = 200 N; AC = 1.20 m, CB = 0.80 m
Correct Answer
C
Correct Option:
Effort = 150 N; AC = 1.33 m, CB = 0.67 m
