A metal sphere has a charge of `-6.5 muC`. When `5xx10^(13)` electrons are removed from the sphere, what would be the net charge on it?

Explanation

To solve the problem, we need to follow these steps:

### Step 1: Identify the initial charge on the metal sphere
The initial charge on the metal sphere is given as:
\[ Q_1 = -6.5 \, \mu C \]

### Step 2: Calculate the charge removed by removing electrons
We know that the charge of one electron is:
