In an oil drop experiment, the charges on oil drops were found as `1.5 xx 10^(-15), 3 xx 10^(-15), 4.5 xx 10^(-15), 6.0 xx 10^(-15)`. Calculate the magnitude of the charge on the electron.

Explanation

To calculate the magnitude of the charge on the electron using the data from the oil drop experiment, we will follow these steps:

### Step 1: Identify the Charges
The charges on the oil drops are given as:
- \( q_1 = 1.5 \times 10^{-15} \, \text{C} \)
- \( q_2 = 3.0 \times 10^{-15} \, \text{C} \)
- \( q_3 = 4.5 \times 10^{-15} \, \text{C} \)
- \( q_4 = 6.0 \times 10^{-15} \, \text{C} \)
