normal
A
first remains constant then decreases
B
remains constant
C
first decreases then increases
D
first increases then decreases
Solution
For $\theta < $ angle of repose $F _{ c }= mg$
For $\theta > $ angle of repose $\operatorname{as} \theta \uparrow \quad f=\mu mg \cos \theta \downarrow$
$N = mg \cos \theta \downarrow$
