Two insulating small spheres are rubbed against each other and placed 1 cm apart. If they attract each other with a force of 0.1 N, how many electrons were transferred from one sphere to the other during rubbing?

Explanation

To solve the problem, we will follow these steps:

### Step 1: Understand the Given Information
We know that two insulating spheres attract each other with a force of \( F = 0.1 \, \text{N} \) when they are \( R = 1 \, \text{cm} = 0.01 \, \text{m} \) apart.

### Step 2: Use Coulomb's Law
According to Coulomb's Law, the force \( F \) between two charges \( Q_1 \) and \( Q_2 \) separated by a distance \( R \) is given by:
