State two characteristic properties of nuclear forces.

Explanation

### Step-by-Step Solution:

1. **Identify the Question**: The question asks for two characteristic properties of nuclear forces.

2. **First Characteristic Property**:
- Nuclear forces are **charge independent**. This means that the strength of the nuclear force does not depend on the electric charges of the particles involved (protons and neutrons). Whether the particles are positively charged (protons) or neutral (neutrons), the nuclear force remains the same.

3. **Second Characteristic Property**:
...
