Answer Details

When two insulated charged spheres of different sizes and opposite charges are connected together by a metallic conductor, electrons will flow from the sphere with a higher negative charge to the sphere with a lower negative charge until both spheres have the same charge magnitude and sign. This process continues until both spheres are at the same potential or voltage. The charges on the spheres distribute themselves evenly over the entire surface of both spheres, and the potential difference between them decreases until it reaches zero. The size of the spheres does not affect this process, but it determines the amount of charge that each sphere can hold. The temperature does not have any significant impact on this process as well. Therefore, the correct option is: "carry the same magnitude and sign of charge" and "are at the same potential."
