A charged object having charge of-4C is given `9xx 10^19` electrons. Calculate the net charge on the object

Explanation

To solve the problem, we need to calculate the net charge on a charged object after adding a certain number of electrons. Here’s a step-by-step solution:

### Step 1: Identify the initial charge of the object
The initial charge of 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:
