What is the acceleration of a particle orbiting around a nucleus?

v/(4(pi)) = a ?

I cannot find this info... Will you help me?

r = r0

If it is a uniform motion it will have radial acceleration of

$$a_r= \frac{v^2}{r}$$

If you really mean a partical orbitting, then it is a=v^2/r.

If you're talking about electron orbitals, not orbits, the electrons are not accelerating. The elecrons do not whip around in a circle around a nucleus. The orbital is the space defined by the probability density function of the electron.

I agree with Njorl
The Que said particle, i.e with definite coordinated and since the forum is in K-12, i didn't delved into probability theory
