Answer:

true 1 and 4

Explanation:

En un conductor que la carga no se mueve.

1. True. Debe ser una superficie equipotencial, para no haya fuerzas sobre la carga

2. False. Si existe un campo eléctrico, debe existir una fuerza, por lo tanto con pueden estar quitas las cargas

3. False. No puede ser cero ya que existe una carga finita

4. True. Con la ley de Gauss podemos considerar la carga concentrador un punto en el centro de la orbita; por lo tanto existe un campo eléctrico perpendicular a la superficie

5. False si el potencial es ero no hay carga
