Three simple harmonic motion of equal am...

Three simple harmonic motion of equal amplitudes `A` and equal time periods in the same direction combine. The phase of the second motion is `60^(@)` ahead of the first and the phase of the third motion is `60^(@)` ahead of the second. Find the amplitude of the resultant motion.

Text Solution

Verified by Experts

The correct Answer is:
A, B
Resultant of `1` and `3` is also `A` in the direction of `2`.

`:. A_(R) = 2A`.
