I cannot find this in my book and i cannot wrap my brain around it...i am more of an analytical person... The question is-A negatively charged balloon is sticking to the wall. Does this mean that the wall is positively charged?Explain.Eventually, the balloon falls down. Explain why. The balloon will stick to the wall longer when the air is dry. Explain Why. 2. None 3. The attempt at a solution Why would we assume the balloon takes on a negative charge and the wall a positive one? The balloon falls, equilibrium is reached and the attractive force is diminished, correct? The balloon sticks to the wall longer when it is dry outside due to the fact that the charges do not dissipate in the dry air as easily as it does on humid days.
