Question

A 50 cm high, 30 cm x 30 cm tank is filled with oil having specific gravity 0.8 upto a depth of 30 cm, what is the maximum acceleration to which tank may be translated on a level road without spilling the oil ? ($g=9.81m/se{c}^2$)

• A. $5.17m/se{c}^2$
• B. $7.35m/se{c}^2$
• C. $9.69m/se{c}^2$
• D. $13.1m/se{c}^2$

Answer 1

The correct option is D $13.1m/se{c}^2$


$weknow;tan\theta =\left(\frac{a}{g}\right)$

$\frac{20}{15}=\frac{a}{g}$

$a=\frac{20}{15}\times 9.81$

$=13.08m/se{c}^2$
