b) oscillation?

Answer 1

Explanation:

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.

Answer 2

Explanation:

• 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.
• Oscillation refers to any Periodic Motion moving at a distance about the equilibrium position and repeat itself over and over for a period of time . Example The Oscillation up and down of a Spring , The Oscillation side by side of a Spring. The Oscillation swinging side by side of a pendulum.
