Two charged conducting spheres are placed close to one another. One sphere is positively charged and the other is negatively charged. Which diagram shows the distribution of charges and the forces acting on the spheres?
This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
Adiagram showing a positively charged sphere with charges concentrated on the side closer to a negatively charged sphere, which has charges concentrated on the side closer to the positive sphere, with arrows indicating attraction between them.
Bdiagram showing a positively charged sphere with charges evenly distributed, and a negatively charged sphere with charges evenly distributed, with arrows indicating attraction between them.
Cdiagram showing a positively charged sphere with charges concentrated on the side closer to a negatively charged sphere, which has charges concentrated on the side closer to the positive sphere, with arrows indicating repulsion between them.
Ddiagram showing a positively charged sphere with charges evenly distributed, and a negatively charged sphere with charges evenly distributed, with arrows indicating repulsion between them.
✓ Correct answer
B: diagram showing a positively charged sphere with charges evenly distributed, and a negatively charged sphere with charges evenly distributed, with arrows indicating attraction between them.
