Q. The effective length of a simple pendulum is the sum of the following three: length of string, radius of bob, and length of hook.
In a simple pendulum experiment, the length of the string, as measured by a meter 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

Solution:

$(92.0+2.15) cm =94.15\, cm$.
Rounding off to first decimal place, we get $94.2\, cm$.
