JEE Main2009PhysicsOscillationsActual
If x, v and a denote the displacement, the velocity and the acceleration of a particle executing simple harmonic motion of time period T , then, which of the following does not change with time?
Options
- Aa^2 T^2+4 ^2 v^2
- Ba T x
- Ca T+2 v
- Da T v
Correct answer
B. a T x
Step-by-step solution
aT X = ^2 XT X = 4 ^2 ~T ^2 T = 4 ^2 ~T = constant.
