Question

A vertical off-shore structure is built to withstand a maximum stress of 108Pa. The structure is suitable for putting up on the top of an oil well in Bombay High at a location where the depth of the sea is less than

(Take g = 10 ms–2 and density of sea water = 1000 kgm–3) 

Solution

Correct option is

10 km

 

Maximum pressure the structure can withstand (P) = 108 Pa. Since the pressure exerted by sea water on the structure of height, 

           

the maximum value of h is 

           

                     

                      = 104 m = 10 km
