The distance between the K+ and Cl− ions in KCl is 2.8 × 10⁻¹⁰ m.
Find the energy required to separate the two ions to an infinite distance apart, assuming them to be point charges initially at rest. The elemental charge is 1.6 × 10⁻¹⁹ C and the Coulomb constant is 8.99 × 10⁹ N ·

Describe the path of the electric current through a circuit?

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
