Question
A small (non-conducting) ball has a charge of +3.00 Times 10^-9 C and a mass of 1.50 Times 10^-5 kg. It is released from rest from the surface of a large positively-charged conducting sheet, until it strikes another conducting sheet which is negatively charged and located 8.0 cm away. There is a 100 V electrical potential difference between the two conducting sheets. What will be the ball's speed when it hits the negatively charged plate? (Assume there are only electrostatic forces involved; no gravity nor air resistance.)Explanation / Answer
