Two positively charged particles are first brought close togetherand then released. Once released, the repulsion betweenparticles causes them to move away from each other.(a) This is an example of potential energy being convertedinto what form of energy? (b) Does the potential energy ofthe two particles prior to release increase or decrease as thedistance between them is increased.
