[tex]F_o=4,5N\ force\ exerted\ by\ object\ is\ downward\\
F_w=4N \ force\ exerted\ by\ water\ is\ upward\\\\Finding\ resultunt\ force:\\\\
F_r=F_w-F_o\\
F_r=4-4,5=-0,5N\ \ sign\ -\ mean\ that\ force\ is\ downward\\\\
If\ resultant\ force\ is\ equal\ to\ -0,5N\ object\ will\ sink.\\ This\ force\ will\ take\ object\ down.[/tex]
