Answer 1

Depth, h = 10 m

Atmospheric pressure, Po = 100000 Pa

Acceleration due to gravity, g = 10 m/s²

Density of water, ρ = 1000 kg/m³

Total pressure at the bottom, P = Po + ρ g h = 100000 + 1000 x 10 x 10 = 200000

(b) 200000 Pa

The apparent loss of weight of a body when immersed in a fluid is the buoyant force. The Buoyant force is calculated using Archimedes principle.

(b) principle of Archimedes.
