Explanation
To answer this question, it is important to understand the concept of tangential velocity in circular motion. Tangential velocity refers to the velocity of an object moving along the tangent to the circle at any point in its path. When an object is in circular motion, such as a ball being swung around in a circle, its velocity at any point is directed along the tangent to the circle at that point. This is because velocity is a vector quantity and always points in the direction of motion of the object.When the ball is released from circular motion, it follows a path that is tangent to the circle at the point of release. This is due to the inertia of the ball, which causes it to continue moving in the direction it was going at the moment of release, which is tangential to the circle.Given the options (I, II, III, IV), the correct answer is the one that shows the velocity vector pointing in the direction tangent to the circle at the point where the ball is located just before being released.
