Hello everyone, we are going to understand this question.
00:05
Here, given in the question, a 950 kilogram cylindrical, can boy floats vertically in salt water? mass of cylinder that is represented by m, which is 950 kilograms.
00:31
The diameter of boy, diameter of boy, that is represented by d, which is 0 .9 meter, calculate the additional distance, the boy, the boy is, will sink when 70 kilogram man stands on top of it.
01:02
The stand mass of the man, mass of man that is represented by m1, which is 75 kilogram, which is 70 kilogram.
01:26
So we have to find that at which height it will sink.
01:33
The sink height be, that the sink height be, the sink height be, the sink height be, now let's draw the free body diagram weight of the cylindrical void that is m into g and thrust force that is f t h and when man stands on this then that is m1 into g and let the height sink is h now now m g plus m1 into g is equal to m -dash into g.
02:51
Here g is will get cancelled.
02:54
Here m -dash -g means thrust force.
02:57
Water replaced by the cylindrical boy.
03:03
So here g is common.
03:05
Value of m is 95, 4 ,950.
03:10
Value of m1 is 70 is equal to m -dash is here.
03:22
Density into volume.
