Question

The vertical height of an almirah is $2m$, its base is a square of side length $0.4m$ and its mass is $200kg$. The maximum height from the floor at which a horizontal force $490N$ should be applied on the almirah so that it does not tilt is:

• A. $0.6m$
• B. $0.8m$
• C. $1m$
• D. $1.2m$

Answer 1

Answer: (B)

$0.8m$

Let the maximum height be $x$ m
by equating Torques
$\Rightarrow F\times x=mg\times \frac{l}{2}$
$490\times x=200\times 9.8\times \frac{0.4}{2}$
$x=0.8m$
