When the sum of all the forces acting on a block on an inclined plane is zero the block?

the block is said to be in equilibrium

Explanation:

When the sum of all the forces acting on the block is zero, the net force acting on the block is zero, hence the balanced forces acting on the block. It means the object is said to be in equilibrium.

Block will be in equilibrium position

Explanation:

When the sum of the forces acting on the block is zero then the block will be ion equilibrium position means there will be no motion on the block.

When force on the block is zero then there will be no acceleration and the will be in rest position this is also called the equilibrium position.

For all forces acting to be zero all the force must be inclioned with some angle
