the force between the electron and the proton.
a) Use F = k * q1 * q2 / d²
where k = 8.99e9 N·m²/C²
and q1 = -1.602e-19 C (electron)
and q2 = 1.602e-19 C (proton)
and d = distance between point charges = 0.53e-10 m
The negative result indicates "attraction".
the radial acceleration of the electron.
b) Here, just use F = ma
where F was found above, and
m = mass of electron = 9.11e-31kg, if memory serves
a = radial acceleration
the speed of the electron.
c) Now use a = v² / r
where a was found above
and r was given
<span> the period of the circular motion.</span>
d) period T = 2π / ω = 2πr / v
where v was found above
and r was given
Answer:
Explanation:
Rutherford gold experiment gave the explanation to some observations made on atoms.
When he shot the gold foil, most of the -particles passes through the foil undeflected nor absorbed. This faction of the particles propagated the foil as if there was nothing placed on their path.
The surprising behavior of a few of the -particles was that they were deflected from their initial path on hitting the gold foil.
This implies that there is a part of the gold foil which has the same charge as the -particles, and more massive than the particles. Thus, he was able to determine the nucleus of an atom.
