The hatch door of a submarine has an area of 0.5m². The specific gravity of sea water Is 1.03. (Assume that g = 10m/s², and neglect the atrnospheric pressure). The force exerted by sea water on the hatch door at a depth of 200m is

• A.1.03 x 10⁵N
• B.1.03 x 10³N
• C.1.06 x 10⁵N
• D.2.06 x 10⁶N
• E.1.03 x 10⁴N
