An oil drop has `6.39 xx 10^(-19)C` charge .How many electrons does this oil drop has ?

Explanation

To find out how many electrons are present in an oil drop with a charge of \(6.39 \times 10^{-19} \, \text{C}\), we can follow these steps:

### Step 1: Identify the charge of one electron
The charge of a single electron is known to be \(1.6 \times 10^{-19} \, \text{C}\).

### Step 2: Use the formula to calculate the number of electrons
To find the number of electrons in the oil drop, we can use the formula:
