Answer:
Effective length of the pendulum: The distance L between the point of suspension and the centre of spherical bob (centre of gravity), L = l + r + e, is also called the effective length where l is the length of the string from the top of the bob to the hook, e, the length of the hook and r the radius of the bob.
