A boat having a length of 5m and breadth 1m is floating on a lake.If a man gets on to the boat,the boat sinks by 1cm.The weight of the man is (Take g=10ms^(-2))

A boat having length 2 m and width 1 m is floating in a lake. When a man stands on the boat, it is depressed by 3 cm. The mass of the man is

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 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

A boat having a length 4m and breadth 2.5 m is floating on lake. The boat sinks by 2 cm when a load is loaded on it. What is the weight of the load ? Use g =10 ms^(-2), density of water = 10^3 kg m^(-3)

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 ?

A boat floating in a lake sinks by 2 cm when a man of mass m gets into it. What will be the mass of man if length and breadth of the boat are 1 m and 2 m?

A boat of length 10m and mass 450kg is floating without motion in still water. A man of mass 50kg standing at one end of it walks to the other end of it and stops. The magnitude of the displacement of the boat in metres relative to ground is
