Rakhi is a student of class 11th, she is strolling in a park near to her house. She saw a fat girl being teased by two thin playmates. They are playing see-saw. Rakhi enquired why they are teasing their playmate and why they are not allowing her to sit on see-saw. Two thin girls replied that it is not possible to play see-saw with the fat girl as she is very heavy for any of them. Rakhi told them if the fat girl sits slightly near towards the middle part then, they can see-saw even with her. And finally that fat girl is see-sawing with one of thin girl. They finally learn to play that game together (i) What technique is told by Rakhi to little girls? (ii) If mass of fat girl is 30 kg and thin girls are of 20 kg (each), then to operate see-saw properly what will be the ratio of their distances from the pivot of plank? (iii) What values are indicated by Rakhi? (iv) What values are indicated by little girls?
