Question

What is the effective length of simple pendulum?

Answer 1

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 92.0cm . The radius of the bob combined with the length of the hook, as measured by a vernier callipers is 2.15cm. The effective length of the pendulum is

92.0cm ,94.2cm,94.15cm,94cm
