Picture a all traveling at a constant speed around the inside of a circular structure. is the ball accelerating? explain your answer

Two identical 82 mg dust particles very far apart (pee 0) are moving directly toward each other at a speed of 3698 m/s. the charge on each is-719 ? c. determine how close they will get to each other. let k = 9x109 n-m2/c2 & ignore gravity.
