What is the force on a submarine window (0.07m2) at 350m depth in seawater (ρ\=1.03×103kg/m3), interior at atmospheric p
Gauge pressure: Pg = ρgh = 1.03×103×10×350 = 3.605×106Pa. F = PgA = 3.605×106×0.07 = 2.5235×105N. As per NCERT, applying relevant law/formula with correct units and sign convention leads to 2.5 × 10⁵ N. This satisfies dimensional consistency and physical conditions given, so option B is scientifically correct.
