Answer 2

The correct answer is option (b) Kinetic energy but not linear momentum.

Explanation:

• Mutual interaction force between two particles can change the Kinetic energy but not linear momentum.
• We can understand this by taking an example.
• Example: When a gun is fired, then it exerts a force on the bullet and in return the bullet exerts a force which to the equal magnitude on the gun (in opposite direction).
• We get know this from the third law of motion.
• The bullet is currently at rest but after firing the gun and bullet attain some kinetic energy.
• Hence, the correct answer is option b i.e Kinetic energy but not linear momentum.
