Solution
The correct option is A Limting For any two surfaces in contact, the magnitude of limiting friction is directly proportional to the normal reaction between two surfaces.
The magnitude of limiting friction is directly proportional to normal reaction(R)
i.e F = μ R
therefore μ = FR
Thus coefficient of limiting friction is the ratio between limiting friction to the normal reaction.
