Question

multiple choice question a ball is being swung on a string. the arrow pointing along the string (a) represents the direction of the ball at that instant velocity of the ball at that instant force on the ball from the string force on the string from the ball

Explanation:

When a ball is swung on a string, the tension force in the string acts along the string. The arrow A pointing along the string represents the force exerted by the string on the ball. The direction of the ball's velocity at an instant is tangent to the circular - path (like arrow B), not along the string. And the force on the string from the ball is in the opposite direction of the force on the ball from the string.

Answer:

C. force on the ball from the string
