Homework Equations
The Attempt at a Solution
Working from the reference frame of block , a pseudo force Ma0 towards right need to be applied on the cylinder .
Forces acting on the cylinder are pseudo force , weight Mg and normal force from the block (if any) .
Since the cylinder does not have horizontal acceleration , N sin30° = Ma0 .
I am not able to proceed from here .
Any help would be appreciated .

. .Friction is a force that opposes the movement of objects in contact with each other. In the case of a block on a horizontal surface, friction acts in the opposite direction of the block's motion, slowing it down or preventing it from moving altogether.
The amount of friction between a block and a horizontal surface depends on the type of surface, the weight of the block, and the force applied to the block. Rough surfaces and heavier blocks typically have more friction, while smoother surfaces and lighter blocks have less friction.
The angle of the surface can affect the movement of the block in two ways. If the surface is inclined, the block will experience a downward force due to gravity, making it harder to move. If the surface is tilted, the block may slide or roll in a specific direction depending on the force applied.
Static friction is the force that must be overcome to set an object in motion, while kinetic friction is the force that opposes the motion of an object. In the case of a block on a horizontal surface, static friction keeps the block from moving until a force is applied, while kinetic friction acts to slow down the block's movement.
The coefficient of friction can be calculated by dividing the force of friction by the normal force between the block and the surface. The normal force is equal to the weight of the block, and the force of friction can be measured by the force needed to move the block or by the acceleration of the block.
