How Fast Does an Electron Travel in a Weak Electric Field with Gravity?

AI Thread Summary
An electron released in a weak electric field of -2.40 x 10^-10 N/C experiences forces from both the electric field and gravity. To find its speed after traveling 1.8 µm, one must calculate the force due to the electric field and the gravitational force, then determine the net force acting on the electron. Using this net force, the acceleration can be calculated, which can then be applied to kinematic equations to find the final speed. Additionally, there is a request for online resources to better understand electric fields and related physics concepts. Understanding these forces and their effects is crucial for solving the problem effectively.

Homework Statement



An electron is released from rest in a weak electric field given by vector E = -2.40 10-10 N/C jhatbold. After the electron has traveled a vertical distance of 1.8 µm, what is its speed? (Do not neglect the gravitational force on the electron.)

Dont even know where to begin.
 
Physics news on Phys.org
Steps to consider:
whats the force on the electron due to the E field?
what about due to gravity?
Whats the net force?
How can you use that information?

do you know of any good online physics resources for electro fields? I am having some trouble understanding everything the professor is teaching, and i know this stuff should be much easier than i am making it!
 
I would find the acceleration of the electron. Then look at your kinematic equations
 

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...
