    A particle is oscillating according to the equation\[X=7\cos 0.5\pi t\], where t is in second. The point moves from the position of equilibrium to maximum displacement in time                                            [CPMT 1989]

    A)            4.0 sec                                     

    B)            2.0 sec

    C)            1.0 sec                                     

    D)            0.5 sec

    Correct Answer: C

    Solution :

                       From given equation\[\omega =\]\[\frac{2\pi }{T}=0.5\pi \]Þ \[T=4\]sec Time taken from mean position to the maximum displacement \[=\frac{1}{4}T=1\]sec.
