Answer:
NEGATIVE
Explanation:
It is Negative beacause POSITIVE and NEGATIVE attract. It's just like a magnet... I think you have tried that if you put the south pole of a magnet close to another south pole of another magnet, then it REPELS right? That's because they don't attract, but if you put south and north together, then they WILL attract to each other.
Same with Positive and Negative Electrons
If the ground is Positive, and the lightning gets attracted to the cloud, that means that the cloud is NEGATIVE
Glossary: (italic words)
Repel - going away from each other
attract - coming even closer to each other
Thanks!
