Pls solve ques. 9th

Dear student,
Please find below the answer:

Option (2) is correct.
As we know,
Pressure=force/area
The surface will break when the force reaches 600+16=616N
Area of circle=pi r^2=6.16m2

Pressure=force/area
              =616/6.16
              =100N/m2
So the maximum pressure should be 100N/m2.

Hope this clears your doubt.
Regards.
