Composition of Two S.H.M."Q.24 Discuss analytically the composition of twoS.H.M.'s of same period and parallel to eachother. Obtain formula for their resultantamplitude and resultant initial phase.Hence, find the resultant amplitude when phasedifference of two S.H.M.s is, i) 0°(0 rad), ii) 180° (π rad), iii) 90° (π/2)iv) 120° (T/3)ORTwo SHM's are represented byx, a, sin (at + α) andx,-a, sin (cot + a). Obtain the expression for thedisplacement, amplitude and initial phase of the
