When an ion accelerates through a potential difference of 2160 V its electric potential energy decreases by 3.46*10-16 J. What is the charge on the ion?

A hot-air balloon is accelerating upward under the influence of two forces, its weight and the buoyant force. for simplicity, consider the weight to be only that of the hot air within the balloon, thus ignoring the balloon fabric and the basket.
