0.0175

Explanation:

enter image source here
angle B= $\frac{π}{12}$ $pi/12$
mass=m=24kg
A=force to keep th object upright $= m g cos B = 24 \cdot 9.81 \cdot cos (\frac{π}{12}) = 227.42 N$ $=mgcosB=24*9.81*cos(pi/12)=227.42N$
F=friction=4N
we know,
co-efficient, $μ = \frac{F}{A}$ $mu=F/A$
$= \frac{4 N}{227.42 N}$ $=(4N)/(227.42N)$

$= 0.0175$ $=0.0175$
