Fig.1.33 shows a uniform metre rule placed on a fulcrum at its mid point O and having a weight 40gf at the 10cm mark and a weight of 20gf at the 90cm mark. (i) Is the metre rule in equilibrium? If not , howwill the turn? (ii) How can the rule be brought in equilibrium by using an additional weight of 40 gf?

1.	Fig.1.33 shows a uniform metre rule placed on a fulcrum at its mid point O and having a weight 40gf at the 10cm mark and a weight of 20gf at the 90cm mark. (i) Is the metre rule in equilibrium? If not , howwill the turn? (ii) How can the rule be brought in equilibrium by using an additional weight of 40 gf?
Answer» Solution :(i) No, The rule will TURN anticlockwise (ii) By PLACING the additional WEIGHT of 40gf at the 70CM mark.
