Question

A water tank has four taps fixed at points A, B, C, and D. The water will flow out at the same pressure from the taps at

• A. B and C
• B. A and B
• C. C and D
• D. A and C

Answer 1

The correct option is A

B and C

The explanation for correct option:

In the case of option (A)

1. The pressure inside the liquid will be equal to the same depth, but the pressure of the liquid will vary with the height of the liquid.
2. When water is allowed to drain from the water tank, points B and C are at the same depth and therefore have the same pressure.
3. The fluid exerts pressure in all directions because the particles in the fluid can move in all directions.

The explanation for incorrect option:

Option (B)

1. In the case of option (B), the depths of A and B are ups and downs so that their pressure is not equal
2. Hence, it is incorrect answer.

Option (C)

1. In the case of option (C), the depths of C and D are ups and downs so their pressure is not equal.
2. Hence, it is incorrect answer.

Option (D)

1. In the case of option (D), the depths of A and C are ups and downs so their pressure is not equal.
2. Hence, it is incorrect answer.

Therefore, choice A is the correct answer.
