Time period of a simple pendulum in a lab at north pole is 3s. If this pendulum is shifted to equator, then what will be new time period at the equator due to rotation of earth ? (Radius of earth = 6,400 km)

Explanation

To find the new time period of a simple pendulum when it is shifted from the North Pole to the equator, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Time Period Formula**:
The time period \( T \) of a simple pendulum is given by the formula:
\[
T = 2\pi \sqrt{\frac{L}{g}}
