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 man is (a) 12 kg (b) 60 kg (c) 72 kg (d) 96 kg

Ac cording to Archimede's principle, when a body is immersed wholly or partly in a liquid at rest, it loses some of its weight. The loss in weight of the body in the liquid is equal to weight of liquid displaced by the immersed part of the body. From this principle, the law of floatation, is dedcued which states : A body will float in a liquid, if weight of liquid displaced by the immersed part of the body is atleast equal to or greater then the weight of the body. Read the above passage and answer the following questions : (i) A boat having a lenght of 3 m and breadth 2m is floating on a lake. The boat sinks by 1 cm when a man gets on it. What is the mass of the man ? (ii) What values of life do you learn from the law of floatation ?
