Question

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.

Explanation:

The electric force between charged objects is inversely - proportional to the square of the distance between them (Coulomb's law). As the distance between the balloon and the hair increases, the electric force decreases. The charge on the balloon and hair does not change in this simple scenario of just moving them apart.

Answer:

The electric force decreases because the distance increases.
