Question

A driver working below the surface of a lake. The density of water in lake is 1000kg/m3. The atmospheric pressure on surface is 1.0x10m5 pa. and gravitational field strength is 10N/kg.
the drive inflate a balloon with air at a depth of 20m and attracted the balloon to a trap of objects.
a) calculate
1) the pressure due to 20m of water.
2) the total pressure at 20m below the surface of lake. ​
