Un electrón se mueve a 7x10^6 m/s en dirección horizontal. Este ingresa en un campo eléctrico vertical uniforme de -7,3x10^3 N/C. Haga un esquema del problema y encuentre el tiempo que tarda el electrón en viajar 3 cm en forma horizontal y su desplazamiento vertical después de haber recorrido esos 3cm en la horizontal. Ignore los efectos gravitacionales.

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?

In a classical model of the hydrogen atom, the electron moves around the proton in a circular orbit of radius 0.053 nm. what is the electron's orbital frequency? what is the effective current of the electron?
