Question

a uniform metre scale balances horizontally on a knife edge placed at 55cm mark when a mdss of 25g is supported from one end. draw the diagram of the arrangement .calculate the mass​

Answer 1

Answer:

As the metre scale is balanced at 55cm mark i.e. large arm is balanced by arm BC and 25g is suspended at one end i.e. at 100cm mark ∴ Anticlockwise moment = clockwise moment W × (55 – 50) = 25 × (100 – 55)W = 25 × 45/5 = 225gRead more on Sarthaks.com - https://www.sarthaks.com/276702/uniform-metre-scale-balances-horizontally-knife-edge-placed-55cm-mark-mass-supported-from?show=276710#a276710
