Question
The Bohr model of the hydrogen atom proposes that the electron orbits around the proton in a circle of radius $5.3 \times 10^{-11} \mathrm{m} .$ The electric force is responsible for the radial acceleration of the electron. What is the speed of the electron in this model?
Step 1
In the case of circular motion, the acceleration is the centripetal acceleration, which is given by the speed squared (v^2) divided by the radius (r). So we have: \[F = m \cdot a = m \cdot \frac{v^2}{r}\] Show more…

The Bohr model of the hydrogen atom proposed that the electron orbits around the proton in a circle of radius $5.3 \times 10^{-11} \mathrm{m} .$ The electric force is responsible for the radial acceleration of the electron. What is the speed of the electron in this model?
In the Bohr theory of the hydrogen atom, an electron moves in a circular orbit about a proton, where the radius of the orbit is $5.29 \times 10^{-11} \mathrm{m} .$ (a) Find the magnitude of the electric force exerted on each particle. (b) If this force causes the centripetal acceleration of the electron, what is the speed of the electron?
In a Bohr model of the hydrogen atom, an electron circles a proton in an orbit of radius 3.75\times 10^(-11)m. The attraction of the proton for the electron furnishes the centripetal force needed to hold the electron in orbit. Find the electron's speed.
