Physics Fluid Mechanics Mix MCQ (Single Correct)

The figure shows two fish tank, each having ends of width 1 foot. Tank A is 3 feet long while tank B is 6 feet long. Both tanks are filled with 1 foot of water.

S A = the magnitude of the force of the water on the end of tank A

S B = the magnitude of the force of the water on the end of tank B

B A = the magnitude of the force of the water on the bottom of tank A

B B = the magnitude of the force of the water on the bottom of tank B Using the notation given above, Which one of the following sets of equations below is correct for this situation?

A
S A = S B and B A = B B
B
S A = 2S B and B A = B B
C
2S A = S B and 2B A = B B
D
S A = S B and 2B A = B B

Verified by Experts
The correct answer is:
D

S A = ( ρ gh) A S B = ( ρ gh) (1ft 2 )

S A = ( ρ gh) (1ft 2 ) B B = ( ρ gh) (6ft 2 )

B A = ρ gh (3ft 2 )

S A = S B ; B B = 2B A
