Question

Select One Option Correct from the following : Three simple harmonic motions in the same direction having the same amplitude and same period are superimposed. If each differ in phase from the next by $45^{o}$, then,
(A)the resultant amplitude is $(1+\sqrt{2}) a$.
(B)the phase of the resultant motion relative to the first is $90^{o}$
(C)the energy associated with the resulting motion is $(3+2\sqrt{2})$ times the is energy associated with any single motion.
(D)the resulting motion is not simple harmonic.

Answer 1

d is correct I think

Answer 2

OPTION $\huge\bold\red{D}$ IS CORRECT...

(A)the resultant amplitude is $(1+\sqrt{2}) a$.

(B)the phase of the resultant motion relative to the first is $90^{o}$

(C)the energy associated with the resulting motion is $(3+2\sqrt{2})$ times the is energy associated with any single motion.

✔️(D)the resulting motion is not simple harmonic.
