**Illustration Description:**
The diagram features a three-dimensional cube with arrows pointing both towards and away from its surfaces. Each arrow is of equal length and represents a field of the same strength. 

The arrows are positioned as follows:
- An arrow points inward from the left face of the cube.
- An arrow points inward from the bottom face of the cube.
- An arrow points inward from the back face of the cube.
- An arrow points outward from the top face of the cube.
- An arrow points outward from the right face of the cube.
- An arrow points outward from the front face of the cube.

**Question:**
Assuming all arrows represent the same strength field, this cube contains:

- ⃝ Net positive charge
- ⃝ No charge
- ⃝ Net negative charge
- ⃝ Equal amounts of positive and negative charge
- ⃝ Cannot tell from diagram

**Explanation:**
The arrows symbolize the direction of the electric field. In the context of charge analysis:
- Arrows pointing inward signify a negative field contribution, thereby indicating negative charge.
- Arrows pointing outward symbolize a positive field contribution, thereby indicating positive charge.
  
In this illustration, there are three arrows pointing inward and three arrows pointing outward:
- 3 arrows inward (negative influence)
- 3 arrows outward (positive influence)

Since the number of inward arrows (negative) equals the number of outward arrows (positive) and the strength of the fields is identical, this cube contains equal amounts of positive and negative charges, resulting in no overall net charge.

**Correct Answer: Equal amounts of positive and negative charge**
