Question

Two balls are thrown simultaneously in air. The acceleration of the center of mass of the two balls when in air,

• A. Is equal to $g$ (Acceleration due to gravity)
• B. Depends on the masses of the two balls
• C. Depends on the direction of motion of the two balls
• D. Depends on the speeds of the two balls

Answer 1

The correct option is A Is equal to $g$ (Acceleration due to gravity)

Both the balls experience the gravitational force. This force is proportional to the mass of the ball.

Thus, acceleration is $\frac{Force}{mass}$ is a constant and is equal to $g$.
