Statement I: The linear momentum of a particle does not depend on the frame of reference.
Statement II: The kinetic energy of a particle does not depend on the frame of reference.
Options
- AStatement I is incorrect, while Statement II is correct.
- BBoth Statement I and Statement II are correct.
- CBoth Statement I and Statement II are incorrect.
- DStatement I is correct, while Statement II is incorrect.
Correct answer
C. Both Statement I and Statement II are incorrect.
Step-by-step solution
The velocity of a particle depends on the frame of reference from which it is observed.
Linear momentum is given by . Since velocity is frame-dependent, linear momentum also depends on the frame of reference. Thus, Statement I is incorrect.
Kinetic energy is given by . Since speed is frame-dependent, kinetic energy also depends on the frame of reference. Thus, Statement II is incorrect.
Both Statement I and Statement II are incorrect.
Linear momentum is given by . Since velocity is frame-dependent, linear momentum also depends on the frame of reference. Thus, Statement I is incorrect.
Kinetic energy is given by . Since speed is frame-dependent, kinetic energy also depends on the frame of reference. Thus, Statement II is incorrect.
Both Statement I and Statement II are incorrect.
