Denoted by μ. The coefficient of static friction represents the maximum value of friction that can exist between two surfaces before one starts sliding relative to the other. In this case, μ represents the maximum value of static friction between block P and platform M.

The coefficient of static friction is a dimensionless quantity and its value depends on the nature of the surfaces in contact. It can be determined experimentally by measuring the maximum force required to initiate sliding motion between the two surfaces.

The coefficient of static friction is typically denoted by the Greek letter μ (mu) and can range from 0 to 1. A value of 0 represents no friction, while a value of 1 represents maximum friction.

To summarize, the coefficient of static friction (μ) between wooden block P and wooden platform M represents the maximum value of friction that can exist between the two surfaces before one starts sliding relative to the other.

Wooden box move relative to platform only in opposite direction since there is no possibility to move with platform in same direction.
box move in opposite direction iff
umg force greater than force due to acceleration .
f= umg
