Question

Statement I: The change in kinetic energy of a particle is equal to the work done on it by the net force.
Statement II: Change in kinetic energy of particle is equal to the work done only in case of a system of one particle.

• A. If both statement I and statement II are true and statement II is the correct explanation of statement I
• B. If both statement I and statement II are true but statement II is not the correct explanation of statement I
• C. If statement I is true but statement II is false
• D. If both statement I and statement II are false
