Highly selective Backlog Qs for JEE MainPhysicsOscillations
When a particle executing SHM oscillates with a frequency v , then the kinetic energy of the particle
Options
- Achanges periodically with a frequency of v
- Bchanges periodically with a frequency of 2 v
- Cchanges periodically with a frequency of v / 2
- Dremains constant
Correct answer
B. changes periodically with a frequency of 2 v
Step-by-step solution
We know that Kinetic energy K= 1 2 m u² where u= d y d t = a t So. K= 1 2 m ² a² ² t Hence, kinetic energy varies periodically with double the frequency of SHM. So, when a particle executing SHM oscillates with a frequency v, then the kinetic energy of particle changes periodically with a frequency of 2 v .
