The hatch door of a submarine has an area of 0.5m². The specific gravity of sea water is 1.03. Assume that g = 10 m/s and neglect the atmospheric pressure. The force exerted by the sea water on the hatch door at a depth of 200m is

• A.1.03 × 10⁵N
• B.1.03 × 10⁵Nm²
• C.2.6× 10³Nm²
• D.2.06 × 10¹¹N
• E.1.03 × 10³N
