$F=mg-\rho Vg$

OR

$F=\left(0.0126\times 9.81\right)-\left(915\times 7.24\times {10}^{-6}\times 9.81\right)$ ✓

$F=5.86\times {10}^{-2} «\mathrm{N}»$ ✓

Accept use of $g\mathit{=}\mathit{10}$ leading to $F=\mathit{6}\mathit{.}\mathit{0}\mathit{\times }{\mathit{10}}^{\mathit{-}\mathit{2}}\mathit{ }N$
