If $\theta$ is equal to $\alpha$ at the time the box is just about to slide down the plank, the coefficient of static friction between the plank and box is

sin $\alpha$

cos $\alpha$

tan $\alpha$

sec $\alpha$

cot $\alpha$

View answer & explanation

Correct answer is C

$\mu = \frac{F}{R} = \frac{W sin \theta}{W cos q}$

= tan $\theta$
