How much time does the bob of a second.s pendulum take to move from one extreme to the other extreme of its oscillation?

Explanation

To solve the question of how much time the bob of a second's pendulum takes to move from one extreme to the other extreme of its oscillation, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of a Second's Pendulum**: A second's pendulum is defined as a pendulum that has a time period of 2 seconds. This means it takes 2 seconds to complete one full oscillation (from one extreme to the other and back).

2. **Identify the Motion of the Pendulum**: The motion of the pendulum can be divided into two halves:
- From the left extreme to the mean position (center).
