Question

In the diagram below the red arrows represent

• A. Tension T applied by the string on the ball acting vertically downward and Gravitational pull (mg) acting vertically upward
• B. Tension T acting vertically upward, applied by the string on the ball and Gravitational pull (mg) acting on the ball acting vertically downward
• C. Reaction of the tensions represented by the blue arrows
• D. The Weights of the string and the ball

Answer 1

The correct option is B

Tension T acting vertically upward, applied by the string on the ball and Gravitational pull (mg) acting on the ball acting vertically downward

The force of gravity due to earth applies a vertically downward force on the ball. The ball in turn exerts the same force on the string. The string applies a reaction force on the ball. This reaction force is called Tension.
