Static Equilibrium and Elasticity

Daniel and Jonathan are playing on the seesaw with their mother in the park. The 6-m long uniform board is hinged at its midpoint. If Daniel and Jonathan weigh 30kg and 20kg and sit at distance of 2m and 3m respectively from the fulcrum, calculate where their mother (mass=60 kg) has to sit on the other side of the fulcrum for static equilibrium.



a) 2.5m
b) 1.5m
c) 1.0m
d) 2.0m
e) none of these

Assume Jonathan and Daniel weigh the same.
