Problem 1 two positive point charges are released on a frictionless surface. which of the following best describes their subsequent motion? select one of the following: (a) the particles remain stationary. (b) the particles move apart with constant velocity. (c) the particles move apart with a velocity that decreases with time. (d) the particles move apart with a velocity that increases with time. (e) the particles move apart with a velocity that increases for a while and then becomes constant.

First, launch the video below. you will be asked to use your knowledge of physics to predict the outcome of an experiment. then, close the video window and answer the question at right. you can watch the video again at any point. part a as in the video, we apply a charge +q to the half-shell that carries the electroscope. this time, we also apply a charge –q to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? view available hint(s) as in the video, we apply a charge + to the half-shell that carries the electroscope. this time, we also apply a charge – to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? it deflects more than it did at the end of the video. it deflects the same amount as at end of the video. it does not deflect at all. it deflects less than it did at the end of the video. submit
