When two displacements represented by $y_{1} = a s i n (ω t)$ and $y_{2} = b \cos (ω t)$ are superimposed the motion is:NEET 2015 (Phase 1)

Options:

Answer:

Solution:

$y_{1} = a \sin ω t$

$y_{2} = b \cos ω t = b \sin (ω t + \frac{π}{2})$

Amplitude $A = \sqrt{a^{2} + b^{2} + 2 a b \cos \frac{π}{2}}$

$A = \sqrt{a^{2} + b^{2}}$

Since the frequency for both motion are same, then the resultant motion will be SHM.
