Question

mission se1: charges and atoms
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.
images of spheres a to h with charge signs omitted as per ocr instruction

Explanation:

Step1: Determine the condition for neutrality

A sphere is neutral when the number of positive charges ($+$) is equal to the number of negative charges ($-$).

Step2: Analyze each sphere

• Sphere A: All are $-$, so not neutral.
• Sphere B: All are $+$, so not neutral.
• Sphere C: 6 $+$ and 2 $-$, not equal.
• Sphere D: 7 $+$ and 1 $-$, not equal.
• Sphere E: 3 $+$ and 5 $-$, not equal.
• Sphere F: 4 $+$ and 4 $-$, equal.
• Sphere G: 4 $+$ and 4 $-$, equal.
• Sphere H: 4 $+$ and 4 $-$, equal.

Answer:

F. Sphere F, G. Sphere G, H. Sphere H
