Two parallel plates are a distance apart with a potential difference between them. A point charge moves from the negatively charged plate to the positively charged plate. The charge gains kinetic energy 800J. The distance between the plates is tripled and the potential difference between them is halved. What is the kinetic energy gained (in joules) by an identical charge moving between these plates
