Superposition of SHMHardQuestion 31174
Question
Two perpendicular SHMs of same frequency and 90° phase difference produce:
- ALinear motion
- BCircular motion (if amplitudes equal)
- CElliptical motion (if amplitudes unequal)
- DBoth B and CCorrect
Correct answer
Both B and C
Explanation
x = A sinωt, y = B sin(ωt+π/2) = B cosωt. If A = B: circle (x²+y²=A²). If A ≠ B: ellipse (x²/A²+y²/B²=1).
