[tex]\text{Since the fulcrum lies in between the load and effort, it is class I lever.}[/tex]
[tex]\text{Mechanical advantage (M.A.) of levers is given by,}[/tex]
[tex]\text{M.A.=effort armload arm=50cm,10cm}[/tex]
[tex]\text{Thus, mechanical advantage , M.A. = 5.}[/tex]
[tex]\text{Given, effort (E)=10N, Load(L)=?}[/tex]
