Question

A balanced lever has two weights on it, the first with mass `4 kg` and the second with mass `9 kg`. If the first weight is `4 m` from the fulcrum, how far is the second weight from the fulcrum?

Answer 1

`1.78m`

Explanation:

apply the formula `F_1 * d_1 = F_2 *d_2`
`4*4=9 * d_2`
`d_2=1.78m`
