Question

A u tube containing a liquid is accelerated horizontally with an acceleration a₀. The separation between the vertical arms is l. Find the difference in the heights of the two arms.

• A. (a) gl/a₀
• A. (b) Zero
• A. (c) gl/a₀
• A. (d) (a₀ – g/g)l

Answer 1

(c)

ma₀ = (ρgh)A or (ρAl) a₀ = ρghA or h = la₀/g
