title: "A solid conducting sphere initially carries a net positive charge \\(+Q\\) and sits isolated in space. The sphere is then connected to Earth, which acts as a ground at zero electric potential, by a thin wire until electrostatic equilibrium is reestablished. Which choice correctly identifies the direction of electron flow through the wire and the direction of conventional current?"

# A solid conducting sphere initially carries a net positive charge \(+Q\) and sits isolated in space. The sphere is then connected to Earth, which acts as a ground at zero electric potential, by a thin wire until electrostatic equilibrium is reestablished. Which choice correctly identifies the direction of electron flow through the wire and the direction of conventional current?

A solid conducting sphere initially carries a net positive charge \(+Q\) and sits isolated in space. The sphere is then connected to Earth, which acts as a ground at zero electric potential, by a thin wire until electrostatic equilibrium is reestablished. Which choice correctly identifies the direction of electron flow through the wire and the direction of conventional current?

- **A.** Electron flow: From the conductor to Earth; Conventional current: From the conductor to Earth
- **B.** Electron flow: From the conductor to Earth; Conventional current: From Earth to the conductor
- **C.** Electron flow: From Earth to the conductor; Conventional current: From Earth to the conductor
- **D.** Electron flow: From Earth to the conductor; Conventional current: From the conductor to Earth
