define angle and coefficient of friction and find the relationship b/n them.
Angle of friction is the maximum angle, at which a body starts sliding. It is denoted byq.
The coefficient of friction is a dimensionless scalar value which describes the ratio of the force of friction between two bodies and the force pressing them together. The coefficient of friction depends on the materials used. It is denoted by µ.
The relation between angle of friction and coefficient of friction is given as:
