A balanced lever has two weights on it, the first with mass #16 kg # and the second with mass #32 kg#. If the first weight is # 7 m# from the fulcrum, how far is the second weight from the fulcrum?
Second weight is
In a balanced lever, the moment of each of the weights should be equal.
Moment is mass of the weight multiplied by its distance from fulcrum.
As first weighs
As lever is balanced, moment of second weight too would be
Hence, it should be at a distance of
