Electric Potential & Kinetic Energy

AI Thread Summary
The discussion revolves around the relationship between electric potential and kinetic energy for an electron moving between points A, B, and C. Point A has a potential of 332 V and point B has 149 V, with the electron gaining kinetic energy K when moving from A to C and 2K when moving from B to C. The confusion arises from the differing kinetic energies despite the higher potential at point A compared to point B. Participants suggest using the work-energy principle, specifically the equation W = q*ΔV, to resolve the contradictions. The key focus is on determining the electric potential at point C and the value of kinetic energy K.

Homework Statement


Points A and B have electric potentials of 332 V and 149 V, respectively. When an electron released from rest at point A arrives at point C, its kinetic energy is K. When the electron is released from rest a point B, however, its kinetic energy when it reaches point C is 2K. What is the electric potential at point C? What is the kinetic energy K?


Homework Equations


I don't know exactly what to use, so I'd rather not list all available equations...


The Attempt at a Solution


I tried using Energy Conservation but kept getting a contradiction. The fact that the electric potential at Point A is larger than the electric potential at Point B but the kinetic energy gained while traveling from A to C is less than that from traveling from B to C is confusing me. Help?

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...
