Two blocks A and B of masses m and M are connected to the two ends of a string passing over a pulley. B lies on plane inclined at angle theta with the horizontal and A is hanging freely as shown. The coefficient of static friction between B and the plane is us. Find the minimum and maximum values of m so that the system is at rest.
In the given diagram:
B (i.e. M) lies on the incline plane
A (i.e. m) is hanging
Theta is the angle of the incline
Both A and B are connected by a pulley.
