A pendulum clock and a wrist watch are taken from the earth's surface to a mountain. What will be the effect on their time periods at the mountain ?

Explanation

To solve the problem of how the time periods of a pendulum clock and a wristwatch are affected when taken from the Earth's surface to a mountain, we can analyze each device separately.

### Step-by-Step Solution:

1. **Understanding the Pendulum Clock:**
- The time period \( T \) of a simple pendulum is given by the formula:
\[
T = 2\pi \sqrt{\frac{L}{g}}
