Calculate Potential Energy of Electron in Bohr Model

AI Thread Summary
To calculate the potential energy of an electron in the Bohr model when moving from infinity to a distance r, one must use the Coulomb potential, which defines the interaction between charged particles. The potential energy can be determined by integrating the electric potential from infinity to the specified distance r. The energy gain during this process is expressed as e multiplied by the change in potential, ΔV. It is important to note that the potential is considered zero at infinity, which simplifies the calculation. Understanding these principles is essential for grasping the foundational concepts in classical electromagnetism and quantum mechanics.

How can I calculate the potential energy of the electron when we bring it from the infinity to the distance r?
 
Physics news on Phys.org
-Use the fact that energy-gain when an electron moves from a to b is given by e*\Delta U. (e = electric charge, \Delta V = difference in potential).
-Use the Coulomb potential for an atom.
-Use the fact that the potential is set to zero at infinity.

Good luck :)
 
So we have to take the integral from infinity to "r" of what?

Have you had classical E&M? I thought such course is a prerequisite for a modern physics/QM class?

Zz.
 
I am pretty confused on it.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
