An object with an initial charge of 4 C is given `9 xx 10^19`additional electrons, Calculate the net charge on the object.

Explanation

To calculate the net charge on the object, we will follow these steps:

### Step 1: Identify the initial charge on the object
The initial charge on the object is given as:
\[ Q_{\text{initial}} = 4 \, \text{C} \]

### Step 2: Determine the charge of one electron
The charge of one electron is:
