Question

(3) \( 2.28 \times 10^{5} \mathrm{~N} \) 28. A tapered pressurised tank for a rocket contains \( 0.25 \mathrm{~m}^{3} \) of kerosene, with mass \( 205 \mathrm{~kg} \). The pressure at the top of the kerosene is \( 2.01 \times 10^{5} \mathrm{~Pa} \). The kerosene exerts a force of \( 16.4 \mathrm{kN} \) on bottom having area \( 0.07 \mathrm{~m}^{2} \). Find the depth of the kerosene. (1) \( 2.1 \mathrm{~m} \) (2) \( 0.29 \mathrm{~m} \) (3) \( 0.414 \mathrm{~m} \) (4) \( 4.14 \mathrm{~m} \)
