Two equally charged particles are held apart and then released from rest. The initial acceleration of the first particle is observed to be and that of the second to be . If the mass of the first particle is , what are (a) the mass of the second particle and (b) the magnitude of the charge of each particle?

Ajogger runs 5.0 km on a straight trail at and angle of 60 south of west . what is the southern component of the run rounded to the nearest tenth of a kilometer

The velocity of a curling stone is due east. what will be the direction of the momentum of the curling stone as it moves?

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
