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?

Answer 1

We all know that when Hiro rubs an inflated balloon on his hair, his hair will stick to it.

But when Hiro will move the balloon away from his head, the electric force decreases because the distance increases, as a result of which the hair wil fall back to the head and will no longer stick to the inflated balloon.
