A boat having a length of 3 m and breadth of 2 m is floating on a lake. The boat sinks by 1 cm when a man gets on it. The mass of the mas is:

A

60 kg

B

62 kg

C

72 kg

D

128 kg

Text Solution

Verified by Experts

The correct Answer is:
A
Weight of a man =wt of water displaced
= volume `xx` density `=3 xx 2xx (1)/(100) xx 10 ^(3) = 60 kg`

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.
