    The mean time period of second's pendulum is 2.00s and mean absolute error in the time period is 0.05s. To express maximum estimate of error, the time period should be written as   

    A)          (2.00 ± 0.01) s

    B)                                  (2.00 +0.025) s

    C)          (2.00 ± 0.05) s

    D)          (2.00 ± 0.10) s

    Correct Answer: C

    Solution :

                          Mean time period T = 2.00 sec               & Mean absolute error \[=\Delta T\]= 0.05 sec.          To express maximum estimate of error, the time period should be written as \[(2.00\pm 0.05)\]sec
