A regular hexagon of mass m and side a is placed on a rough surface of coefficient of friction $μ$ . If the hexagon topples before slipping, then :-

Answer:

Solution:

Toppling about the edge: $F \times 3 a = m g \times \frac{a 3}{2}$

$F = \frac{m g}{2}$ ; for no slipping $F \leq μ m g$ , so $μ \geq \frac{1}{2}$
