Hiro rubs an inflated balloon on his hair, and his hair sticks to the balloon. As he moves the balloon away from his head, how does the electric force change? The electric force increases because the balloon loses its charge.
The electric force increases because the distance increases.
The electric force decreases because the distance increases.
The electric force decreases because his hair loses its charge

The electric force decreases because the distance increases.

Explanation:

As the distance increases, the electric force will be weakened and will decrease in return.

So, since Hiro moved the balloon away from his head, the distance between his head and the balloon will increase.

This will lead to a decrease in the electric force due to the increase in distance.

i think it is dna, i'm not totally sure but i think it might be.
