First slide

Toppling

Question

A cubical block of side L rests on a rough horizontal surface with coefficient of friction p. A horizontal force F' is applied on the block as shown. If the coefficient of friction is sufficiently high so that the block does not slip before toppling, the minimum force required to topple the block is:

Moderate

A

infinitesimal
B

mg/4
C

mg/2
D

mg(1 - $μ$ )

Solution

FBD of block in case of toppling
About point O, $τ_{F} \geq τ_{mg}$
So, FL ≥ mg (L/2)
$\Rightarrow F \geq \frac{mg}{2}$
