Question

A rectangular container with base  contains 5 kg of water. What is the pressure exerted by water at the bottom of the container? 

Solution

Correct option is

9800 Pa

 

Force exerted by 5 kg of water (F), 

         

      

  

                                                             

  

                      

                      = 9800 Nm–2 or Pa.
