Find in degrees the angle through which a pendulum swings if its length is `50c m` and the tip describes an arc of length `10c m` .

Explanation

To find the angle through which a pendulum swings, we can use the relationship between the arc length, the radius, and the angle in radians. Here’s a step-by-step solution:

### Step 1: Identify the given values
- Length of the pendulum (radius, r) = 50 cm
- Arc length (s) = 10 cm

### Step 2: Use the formula for the angle in radians
The formula to find the angle (θ) in radians when given the arc length (s) and the radius (r) is:
