If the kinetic energy of a particle is increased by 300%, the momentum of the particle will increase by:

1. 20%
2. 200%
3. 100%
4. 50%

Correct answer: 100%

Solution

Kinetic energy (K) is proportional to the square of momentum (p), i.e., K ∝ p². If K increases by 300%, it becomes 4K. Thus, p increases by a factor of √4 = 2, which is a 100% increase.
