En el modelo de Bohr simple del estado fundamental del átomo de hidrógeno, el electrón viaja en una órbita circular alrededor de un protón fijo. El radio de la órbita es $5,28 \times 10^{-11} \mathrm{~m}$, y la rapidez del electrón es $2,18 \times 10^6 \mathrm{~m} / \mathrm{s}$. La masa de un electrón es $9,11 \times 10^{-31} \mathrm{~kg}$. ¿Cuál es la fuerza sobre el electrón?

Key Concepts

Electrostatic Force (Coulomb's Law)

Electrostatic force, described by Coulomb's Law, is the attractive or repulsive force between charged particles. In the Bohr model, the electron and the proton experience an electrostatic attraction, and this force supplies the necessary centripetal force to maintain the electron's circular orbit.

Centripetal Force

Centripetal force is the net force directed towards the center of a circular path that keeps an object moving along that path. It is quantified by the equation F = m*v²/r, where m is the mass of the object, v is its speed, and r is the radius of the circle.

Bohr Model

The Bohr model is an early quantum theory model which describes electrons in an atom as moving in fixed, circular orbits around the nucleus with quantized energy levels. This model explains atomic spectra by allowing only specific orbits where electrons can reside, each corresponding to a particular energy level.

Circular Motion

Circular motion refers to the movement of an object along a circular path. Even when the speed is constant, the continuous change in direction constitutes acceleration, known as centripetal acceleration, which requires a net inward force.
