Question

Acceleration of the freely falling metal rod in a cycling ring?

• A. \( g \)
• B. \( 2g \)
• C. \( 0 \)
• D. \( g/2 \)

Hint:

For freely falling objects near Earth's surface, the acceleration is always \( g \), which is approximately \( 9.8 \, \text{m/s}^2 \).

Answer 1

The Correct Option is A

When a metal rod is freely falling in a cycling ring, it experiences an acceleration equal to the acceleration due to gravity, \( g \). Since the rod is under the influence of gravity only, the force acting on it is the gravitational force, and hence the acceleration of the rod is \( g \), which is the acceleration due to gravity. Thus, the acceleration of the freely falling metal rod is \( g \).
