Problem

A diver initially rests at a depth of

6\,\text{m}

in seawater of density

1025\,\text{kg\,m}^{-3}

. He then descends to a depth of

20\,\text{m}

. (a) Find the gauge pressure acting on the diver at

6\,\text{m}

. (b) Calculate the additional force exerted on the diver’s flat chest area of

0.15\,\text{m}^{2}

when he moves from

6\,\text{m}

20\,\text{m}

. (Take

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