The focal length of a convex lens was measured a number of time.s The mean focal length was found to be 10.41 cm. If the mean absolute error in the value of focal length is 0.13 cm. Calculate the relative error and the percentage error.

Explanation

To solve the problem, we need to calculate the relative error and the percentage error based on the given mean focal length and the mean absolute error.

### Step-by-Step Solution:

1. **Identify the given values**:
- Mean focal length (f_avg) = 10.41 cm
- Mean absolute error (Δf_avg) = 0.13 cm
