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 of how many electrons were transferred from one insulating sphere to another when they attract each other with a force of 0.1 N, we can follow these steps:

### Step 1: Understand the relationship between force, charge, and distance
The force \( F \) between two charged objects can be described by Coulomb's Law:
\[ F = k \frac{|q_1 \cdot q_2|}{r^2} \]
where:
