Question

the charges on several spheres are shown. which spheres are neutral? (note that there are 8 individual charge signs on each sphere.) include all that apply.

Explanation:

A neutral sphere has an equal number of positive (+) and negative (-) charges. We need to count the number of + and - charges on each sphere.

• Sphere A: Count the + and - charges. There are 4 + and 4 - charges. So, it is neutral.
• Sphere B: Count the + and - charges. There are 5 + and 3 - charges. So, it is not neutral.
• Sphere C: Count the + and - charges. There are 6 + and 2 - charges. So, it is not neutral.
• Sphere D: Count the + and - charges. There are 5 + and 3 - charges. So, it is not neutral.
• Sphere E: Count the + and - charges. There are 4 + and 4 - charges. So, it is neutral.
• Sphere F: Count the + and - charges. There are 0 + and 8 - charges. So, it is not neutral.
• Sphere G: Count the + and - charges. There are 6 + and 2 - charges. So, it is not neutral.
• Sphere H: Count the + and - charges. There are 8 + and 0 - charges. So, it is not neutral.

Answer:

A. Sphere A, E. Sphere E
