Two boys weighting 25kg and 35kg sit on ...

Two boys weighting 25kg and 35kg sit on either end of a light pole. Find the point about which the pole remains horizontal if the pole is 6m long. (march-2006 North)

Text Solution

Verified by Experts


`F_1bar(AO)=F_2bar(BO)`
`25xxcancel(9.8)(6-x)=35xxcancel(9.8)(x)`
`150-25x=35x`
`150=60x`
`x=((150)/(60))=2.5m`
Fulcrum should be at 2.5m away from 'B'
