Question

A balanced lever has two weights on it, the first with mass `2 kg` and the second with mass `3 kg`. If the first weight is `7 m` from the fulcrum, how far is the second weight from the fulcrum?

Answer 1

`x=14/3" "m`

Explanation:

`G_1=m_1*g=2g`

`G_2=m_2*g=3g`

`G_1*7=G_2*x`

`2cancel(g)*7=3cancel(g)*x`

`14=3x`

`x=14/3" "m`
