A) \[h\,\rho g\]
B) \[h\,\rho (g-a)\]
C) \[h\,\rho (g+a)\]
D) \[2h\,\rho \left( \frac{g+a}{g-a} \right)\]
Correct Answer: C
Solution :
When a beaker containing a qui d of density p moves up with an acceleration a, it will work as a lift moving upward with acceleration a. The effective acceleration due to gravity in lift \[=(a+g)\] \[\therefore \] Pressure of liquid of height \[h=h\,\,\rho \,\,(a+g)\]
