What will be the pressure at the bottom of a cyllindrical vessel, when the vessel is under free fall?

Option: 1

\rho gh 


Option: 2

0


Option: 3

\rho g a

Where 'a' is the acceleration of the cyllindrical vessel


Option: 4

In free fall, the fluid is moving downward with acceleration equal to the free-fall
acceleration of the Earth. Thus, the acceleration of the fluid is

                                     a = g
 

To obtain the pressure variation of the fluid at free-fall, substitute g for a  in the equation - 

                                   P_{\text {Free }}_{\text {fall }}=\rho A h(g-a)

                                  \begin{aligned} P_{\text {Free fall }} &=\rho A h(g-a) \\ &=\rho A h(g-g) \\ &=0 \end{aligned}
