A perpendicular force of 600 N acts on a circular
surface of radius 1.4 m. The surface will just break
if an additional perpendicular force of 16 N is applied
on it. The maximum pressure that the surface can
withstand is
(1) 50 Pa (2) 100 Pa
(3) 175 Pa (4) 200 Pa.

Pressure=force/area
Force = 600N
Total maximum force= 600+16=616N
Area--> area of a circle= πr^2
= π×1.4×1.4
= 6.16
Pressure= 616/6.16 = 100 pa.
Therefore the correct answer is (2) 100 Pa
