The effective length of a simple pendulum is the sum of the following three length of string , radius of bob, length of hook. In a simple pendulum experiment , the length of the string, as measured by a metre scale is $92.0\;cm$ . The radius of the bob combined with the length of the hook, as measured by a vernier callipers is $2.15\;cm$ The effective length of the pendulum is
