Three simple harmonic motion in the same direction having the same amplitude a and same period are superposed. If each differs in phase from the next by 45°, then The resultant amplitude is (1-2v2))a A) (B) (C) The phase of the resultant motion relative to the first is 90° The energy associated with the resulting motion is (3+22) times the energy as associated with any single motion (D) The resulting motion is not simple harmonic
