9. Figure (4-Q4) shows a boy pulling a wagon on a road.List as many forces as you can which are relevant withthis figure. Find the pairs of forces connected byNewton's third law of motion.Figure 4-Q4

Answer»

Pairs of forces connected by Newtons third law of motion are F-F, R1-R1, R2-R2, R3-R3 and R-R. Though other forces are also connected byNewtons third law of motionbut they do not show as pairs in the figure. Weight W1 and W2 are distributed on the wheels according to loading patterns and C.G. of the wagon and the floor reactions P1 and P2 are according to the net force downwards on the wheels.
