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

Two forces of 6N and 8N act on a body of mass 7 kg. The value of acceleration produced can not be more than :
2m/s²
4 m/s²
6 m/s²
8 m/s²

Short Solution (Best for NEET):

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:

Maximum resultant force will act on the object when 6N and 8 N forces will be acting in same direction. F max= 14 N.

Maximum Acceleration= Maximum Force/ mass= 14 N/ 7 kg = 2m/s²
