NEETPhysicsOscillations
Given blow are two statements: Statement I : In linear SHM net force always act in the direction of velocity. Statement II : In linear SHM direction of velocity changes. In light of above statement choose the most appropriate answer from the options given below:
Options
- ABoth statement I and statement II are correct.
- BStatement I is correct and statement II is incorrect.
- CStatement I is incorrect and statement II is correct.
- DBoth statements I and statements II are incorrect.
Correct answer
C. Statement I is incorrect and statement II is correct.
Step-by-step solution
- Statement I: In linear SHM, the net force does not always act in the direction of velocity. This is incorrect because in SHM, the restoring force always acts towards the mean position, opposite to the displacement. Therefore, when the particle is moving away from the mean position, the force acts opposite to the velocity. - Statement II: In linear SHM, the direction of velocity changes. This is correct because as the particle oscillates back and forth, its velocity changes direction when it crosses the mean posit
