A pendulum dork depends on the period of a pendulum to keep correct time. Suppose a pendulum dock is keeping correct time and then Dennis the Menace slides the bob of the pendulum downward on the oscillating rod. Does the clock run (a) slow, (b) fast, or (c) correctly?

To determine
How the functioning of a pendulum clock changes when the bob slides downwards on the oscillating rod.

Explanation

The period of a simple pendulum which is having a bob of mass m which is suspended by a light string of length L is given by,

T=2πLg

Here,

T is the time period of the simple pendulum

L is the length of the string which suspend the bob of the pendulum

g is the free fall acceleration

When the bob slides downward the oscillating rod, the length L will increase
