Question
A body has 60kg weight. He wants to swim in a river with the help of a wooden log. If relative density of wood is 0.6 what is the minimum volume of wooden log ?
Options
A.0.66m3
B.150m3
C.
m3
m3 D.
m3
m3 Solution
Archimedes principle states that weight of body displaced by liquid = upthrust.
60 × + V × 0.6 × 103 g = V × 1000g
60 + 600V = 1000V
60 = 400V
V =
m3
60 × + V × 0.6 × 103 g = V × 1000g
60 + 600V = 1000V
60 = 400V
V =
