Question

A balanced lever has two weights on it, the first with mass `5 kg` and the second with mass `60 kg`. If the first weight is `6 m` from the fulcrum, how far is the second weight from the fulcrum?

Answer 1

`b=1/2=0,5 m`

Explanation:

`F_1:" First weight"`
`F_2:" Second weight"`
`a:" distance between F_1 and fulcrum"`
`b:" distance between F_2 and fulcrum"`
`"you can write balance equation by:"`
`F_1*a=F_2*b`
`5*6=60*b`
`cancel(30)=cancel(60)*b`
`b=1/2=0,5 m`
