Answer: Larger sphere gets more charge.
- A Larger sphere gets more charge
- B Smaller sphere gets more charge
- C Both get equal charge
- D Charge stays where it was
Correct answer: A. Larger sphere gets more charge
Explanation: Connected spheres equalize potential: V = kQ/r. Larger sphere (2r) needs more charge Q' to have same V as smaller sphere.

Field lines (radial) and equipotential lines (concentric circles) of a point charge. Equipotential surfaces are always perpendicular to the field lines. Image: Sjlegg, Public Domain, via Wikimedia Commons.
Concept context
Electric potential, equipotential surfaces, potential energy of charge systems, conductors, dielectrics, capacitors, combinations, and energy storage.
