A swimmer wears a heavy belt to make her
average density exactly equal to thedensity of water (ρ=1000kgm3).
Her mass, including the belt, ( m= 60 kg ) .
a) The swimmer's weight
W=mg
=60kg9.8ms2
=588N
b) The swimmers volume
V=mρ
=0.06m3
c) At a depth of ( h = 2 m ) below the surface of a pond,
Since:
average density of person = density of water (ρ=1000kgm3)
The bouyant force acts on the swimmer
F=Vwaterρwaterg
=0.0610009.8N
588N
At a depth of ( h = 2 m ) below the surface of apond,
She feels Two force
(i) The bouyant force
(ii) Due to atmospheric-pressure
