NTA Abhyas JEE Main2020PhysicsOscillationsPractice
A particle is subjected simultaneously to two SHMs, one along the x -axis and the other along the y -axis. The two vibrations are in phase and have unequal amplitudes. The particle will execute
Options
- AStraight line motion
- BCircular motion
- CElliptic motion
- DParabolic motion
Correct answer
A. Straight line motion
Step-by-step solution
Let the equations of the two mutually perpendicular SHM's of the same frequency and same phase be x = a 1  sin  ⁡ ω t and y = a 2   sin   ⁡ ω t Then, y x = a 2 sin ω t a 1 sin ω t = a 2 a 1 y = a 2 a 1 x , which is the equation of a straight line
