Calculate the absolute pressure at a point

10\,\text{m}

below the free surface of a lake. Take density of water

=1000\,\text{kg m}^{-3}

g = 9.8\,\text{m s}^{-2}

and atmospheric pressure

P_{0} = 1.01\times10^{5}\,\text{Pa}

. (a)

1.50\times10^{5}\,\text{Pa}

(b)

2.0\times10^{5}\,\text{Pa}

(c)

1.11\times10^{5}\,\text{Pa}

(d)

9.8\times10^{4}\,\text{Pa}
