A cardboard strip, bent in the shape of the letter C, is put on a rough inclined plane, as shown in the figure.What should be the coefficient of friction so that it does not slide before toppling.

Options:

Answer:

Solution:

For it to not slide, $3 m g sin α \leq 3 μ m g cos α$ .

This implies $tan α \leq μ$ .

Given $tan α = \frac{2}{3}$ , we have $\frac{2}{3} \leq μ$ , so $μ \geq 0.66$ .
