Question

A tank is 1.50 m square and 1 m height, it is completely filled with water. How high must its sides be if no water is to be spilled when acceleration is 4 $m/s^2$ parallel to a pair of sides ?

• A. 1.306 m
• B. 1.508 m
• C. 1.866 m
• D. 1.426 m

Answer 1

The correct option is A 1.306 m


$tan\theta =\frac{a_x}{g}=\frac{4}{9.81}$

$\Rightarrow x=\frac{4}{9.81}\times \frac{1.5}{2}=0.306$

$\Rightarrow (1+x)=1.306m$
