    A particle moves on the X-axis according to the equation x = A + B sin ωt. The motion is simple harmonic with amplitude
    (a) A
    (b) B
    (c) A + B
    (d)
    A2+B2.
    digAnsr:   b
    Ans : (b) B
    At t = 0,
    Displacement `` \left({x}_{0}\right)`` is given by,
    x0 = A + sin ω(0) = A
    Displacement x will be maximum when sinωt is 1
    or,
    xm = A + B
    Amplitude will be:
    xm `` -`` xo = A + B `` -`` A = B
