- A boat having a length 3 m and breadth 2 m is floating on a lake.
Question 1:
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 into it.The mass of the man is :
A. 50 kg
B. 60 kg
Feedback In this type of question, first we will calculate the volume of water displaces then will multiply with the density of water.
Volume of water displaced = 3*2*0.01 = 0.06 m cube
Mass of Man = Volume of water displaced * Density of water = 0.06 * 1000 = 60 kg
Volume of water displaced = 3*2*0.01 = 0.06 m cube
Mass of Man = Volume of water displaced * Density of water = 0.06 * 1000 = 60 kg
C. 70 kg
D. 80 kg
These questions are from this test. Would you like to take a practice test?
