A boat having a length 3 m and breadth 2 m is floating on a lake. The boat sinks by 1 cm when a man gets on it. The mass of the man is:
12 kg
60 kg
72 kg
96 kg
Explanation:
Volume of water displaced = (3 x 2 x 0.01)$m^3$
= $0.06 m^3.$
ஃ Mass of man = Volume of water displaced x Density of water
= (0.06 x 1000) kg
= 60 kg.
Volume of water displaced = (3 x 2 x 0.01)$m^3$
= $0.06 m^3.$
ஃ Mass of man = Volume of water displaced x Density of water
= (0.06 x 1000) kg
= 60 kg.
