Linear Momentum and Second Law of Motion: Practice Problem & Solution

Solution Explained:

To solve this problem, we apply the core principles of Linear Momentum and Second Law of Motion. Understanding the underlying formula is key to arriving at the correct answer below:

Assertion (A) is false; zero acceleration implies zero \(\text{net}\) force, not zero individual forces. Reason (R) is false; a single force causes \(text{acceleration}\) in its direction, not necessarily motion in that direction if initial velocity is present.
