Homework problem - MasteringPhysics.com (electric potential)

AI Thread Summary
The discussion centers on calculating the electric potential of a proton at the position of an electron in a hydrogen atom, where the electron orbits at a distance of 0.053 nm. Participants are seeking the equation for electric potential due to a point charge and how to apply it to find the electron's potential energy. Clarification is requested on whether to use the area of a circle in the calculations or if constants should be included in the solution. The conversation emphasizes understanding the fundamental concepts of electric potential and potential energy in a semiclassical model. Accurate calculations are essential for mastering these physics concepts.

In a semiclassical model of the hydrogen atom, the electron orbits the proton at a distance of 0.053nm.


What is the electric potential of the proton at the position of the electron?

What is the electron's potential energy?




(do i use the area on a circle in this equation? or is this an answer with constants in the solution?) if you guys could help me figure this out I would appreciate it.
thank you.

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'

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...
