1.	A, B and C are three forces each of magnitude 4N acting in the plane of paper as shown in fig.1.26 Point O lies in the same plane. (i) Which force has the least moment about O? Give reason. (ii) Which force has the greatest moment about O? Give reason. (iii) Name the forces producing (a) clockwise , (b) anticlockwise moments. (iv) What is the resultant torque about the point O?
Answer» SOLUTION :(i) C, because force C is NEAREST to O (ii) A, because force A is farthest from O (iii) (a) A and B (b) C (IV) 4.4 N m (CLOCKWISE)
