The atmospheric pressure due to water is 1.3 x 10⁶Nm^-2. What is the total pressure at the bottom of an ocean 10m deep? [Density of water = 1000kgm^-3, g = 10ms^-2]

1.3 x 10⁷Nm^-2

1.4 x 10⁶Nm^-2

1.4 x 10⁵Nm^-2

1.0 x 10 ⁵Nm^-2

Correct answer is B

Pressure = heg = 1000 x 10 x 10 = 10⁵Nm^-2

Total pressure = (1.3 x 10⁶) + (1 x 10⁵)

= 1.4 x 10⁶Nm^-2
