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 , how will the turn?
(ii) How can the rule be brought in equilibrium by using an additional weight of 40 gf?

Text Solution

Verified by Experts

(i) No, The rule will turn anticlockwise
(ii) By placing the additional weight of 40gf at the 70cm mark.
