1
Pressure formula in a fluid:
Answer & explanation
Correct: option B
p = hρg gives pressure at depth h.
2
Pressure 4 m deep in water (ρ = 1000, g = 9.8):
Answer & explanation
Correct: option D
p = 4 × 1000 × 9.8 = 39,200 Pa.
3
Doubling depth in water:
Answer & explanation
Correct: option B
p ∝ h.
4
Pressure in a fluid acts:
Answer & explanation
Correct: option C
All directions at a given depth.
5
Why are dams thicker at the bottom?
Answer & explanation
Correct: option B
Pressure increases with depth → base must withstand more force.
6
Two containers — narrow and wide — have water 2 m deep. Pressure at the bottom is:
Answer & explanation
Correct: option C
Pressure depends on h alone (and ρ, g), not on width.
