If Jessica weighs 45kg and sits on a seesaw at a distance of 2m from the centre of the seesaw.Micheal weighs 90kg. At what point on the opposite side should Micheal sit in order to balance the seesaw.

GCSE

Micheal should sit at a distance of 1m from the pivot or half whatever distance Jessica sits. This is found intuitively here but can be found with any two masses by resolving moments.
