Answer 2

${\bold {\huge {\red{Answer :}}}}$

the angle that a surface of contact between two things makes with the horizontal when the thing is just about to slide the angle whose tangent is the coefficient of friction between the two things 2 or angle of rest the angle of maximum slope at which the body gets reposed is in the range of 0° to 90°.

when the body is just about to move, the size of the friction is given by

$F_r= mg sin\theta \: = xR \:$

where x=coefficient if friction.
