two small kids weighing 10kg and 15kg are trying to balance on a seesaw of total length 5 m with the fulcrum at the centre. if one of the kids is sitting at an end where should the other sit?

Answer 1

W1*d1 = W2*d2.

10 * 2.5 = 15*d2.
d2 = 25/15 = 1.67 m. from the center.
d2 = 2.5-1.67 = 0.83 m. from the end.
