The string must provide the necessary centripetal force to move the ball in a circle. If the string breaks, the ball will move off in a straight line. The straight line motion in the absence of the constraining force is an example of Newton's first law                        Newton's 2nd Law - Newton's Second Law  applies to a wide range of physical phenomena, but it is not a fundamental principle

Newton's 2nd Law enables us to compare the results of the same force exerted on objects of different mass.                         Newton's 3rd Law -  All forces in the universe occur in equal but oppositely directed pairs. There are no isolated forces; for every external force that acts on an object there is a force of equal magnitude but opposite direction which acts back on the object which exerted that external force

Newton's third law can be illustrated by identifying the pairs of forces which are involved in supporting the blocks on the spring scale.
Friction - the resistance that one surface or object encounters when moving over another.
