A ship's anchor of density $\displaystyle 7500 \mathrm{~kg} / \mathrm{m}^3$ appears $\displaystyle 196$ N lighter when completely submerged in water of density $\displaystyle 1000 \mathrm{~kg} / \mathrm{m}^3$ than in air. The anchor's weight in air will be \_\_\_\_ N.
(Take $\displaystyle \mathrm{g}=9.8 \mathrm{~m} / \mathrm{s}^2$ )
Official answer
(4)
$\displaystyle 1470$
