प्रश्न
What is a simple pendulum? Is the pendulum used in a pendulum clock simple pendulum? Give reason to your answer.
उत्तर
A simple pendulum is a heavy point mass (known as bob) suspended from a rigid support by a massless and inextensible string.
No, the pendulum used in pendulum clock is not a simple pendulum because the simple pendulum is an ideal case. We cannot have a heavy mass having the size of a point and string having no mass.
