Speed of an Electron in an Electric Field

AI Thread Summary
The discussion revolves around calculating the final speed of an electron released between two positive point charges. The user is confused about the relevant equations and concepts, particularly regarding electric fields, forces, and energy conservation. They have calculated initial and final potential energies but are unsure how to proceed to find the electron's speed. A key point raised is that energy is conserved, and the difference in potential energy will relate to the kinetic energy at the final position. Understanding this relationship will enable the user to determine the electron's final speed.

Homework Statement



. Homework Statement

Two stationary positive point charges, charge 1 of magnitude 3.25 nC and charge 2 of magnitude 1.55nC , are separated by a distance of 57.0cm . An electron is released from rest at the point midway between the two charges, and it moves along the line connecting the two charges.

find Vfinal of the electron when it is 10.0 cm from charge 1 the want the final answer in m/s

i don't get any of this my professor went to fast. can anyone help?

What is the equation for the electric field due to a point charge?

What is the equation for the force on a charge due to an electric field?

What is the equation relating force, mass and acceleration?

What is the equation of motion of a mass experiencing a force?
 
I figured out the Uinital=-2.42e-17J, Kinitial= 0J, Ufinal is -5.15e-17J where do i go from here
 
Hi HELLO11,

Energy is conserved in this situation; but Uinitial is not equal to Ufinal. In what form is the rest of the energy at the final point? Once you have that you'll be able to find the speed of the electron.
 

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...
