1.	A uniform metre scale is balanced at the 20 cm mark when masses of 100 g and 50 g are suspended fromthe 10 cm and 30 cm marks respectively. Calculatethe mass of the metre scale.(Ans. 16.67 g)
Answer» Weight of the scale = 66.66gfExplanation:Let's DENOTE the weight of the scale by 2.The scale is 20cm and 100gf is suspended on one end (0 mark) when balanced.So the weight of longer arm i.e. BC is balanced by 100gf So CW moment = A.C.W moment W × 30 = 20 × 100= 2000 / 30= 66.66gfA weight of 100gf should be suspended at ZERO mark.if it HELPS u click on THANKS❤️
