**Understanding Charge Redistribution in Conducting Spheres**

**Question:**

Two conducting spheres are brought into contact. When they are touching each other, what is the charge in Coulombs on the left-most sphere?

**Explanation and Figure:**

![Diagram of Conducting Spheres](Fig. 21-12(1))

The diagram shows two spheres depicted as purple circles. The left sphere is labeled with a charge of +6e, and the right sphere is labeled with a charge of -4e.

**Understanding Charges:**

1. **Initial Conditions:**
   - Left sphere: +6e
   - Right sphere: -4e

2. **When Brought into Contact:**
   - When the spheres touch, charge redistribution occurs until they reach electrostatic equilibrium. 

3. **Total Initial Charge:**
   - Total initial charge: +6e + (-4e) = +2e

4. **Charge Redistribution:**
   - Assuming the spheres are identical, the charge will be evenly distributed between the two spheres.
   - Therefore, each sphere will have a charge of: 

     \( \frac{+2e}{2} = +1e \)

**Answer Box:**

The left-most sphere will have a charge of:

\[ \text{Charge} = \boxed{+1e} \]

Note: If 'e' represents the elementary charge (approximately \( 1.602 x 10^{-19} \) Coulombs), you can convert this value into Coulombs as needed. For the purpose of this problem, we denote charge in terms of elementary charges 'e'.
