Q. 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:
✅ Correct Answer: (B)
60 kg
Explanation: Volume of water displaced
= (3 x 2 x 0.01) m^3
= 0.06 m^3.
∴ Mass of man = Volume of water displaced x Density of water
= (0.06 x 1000) kg
= 60 kg.
Explanation by: Lokendra Rathod
Volume of water displaced
= (3 x 2 x 0.01) m^3
= 0.06 m^3.
∴ Mass of man = Volume of water displaced x Density of water
= (0.06 x 1000) kg
= 60 kg.
= (3 x 2 x 0.01) m^3
= 0.06 m^3.
∴ Mass of man = Volume of water displaced x Density of water
= (0.06 x 1000) kg
= 60 kg.
