MP Board · Class 11 · Physics · Laws of MotionThe angle of friction ($\lambda$) and the angle of repose ($\theta$) are related as:
Step-by-Step Solution
The angle of friction is equal to the angle of repose for a given pair of surfaces in contact, i.e., $\lambda = \theta$. Both are equal to the inverse tangent of the coefficient of static friction.
