oh... derpy me thank you for pointing out my mistake... I know what i did now... i thought that was were i went wrong but i just could not see what it was

Homework Statement An electron is placed in an xy plane where the electric potential depends on x and y as shown in the figure (the potential does not depend on z). The scale of the vertical axes is set byVs = 500 V. In unit-vector notation, what is the electric force on the electron...

Hi, i did figure it out. thankyou. we do not have all the other variables it turned out to be a radial proportionality question, epsilon naught is an electric permittivity constant. in future i will be more specific. thankyou for the break dow of the problem it did however increase my...

hello :P

Yay is a joyous exclaimation if i start at part a) i get Fr=σq/4πεoR^2 then the ratio is F=0.79Fr but how do i get r on its own?

Hello everybody, this is a new member introduction I guess, I'm studying physics and have been geeking out over physics for many years, I just haven't been able to get her but now I am YAY! me

Homework Statement Assume that a ball of charged particles has a uniformly distributed negative charge density except for a narrow radial tunnel through its center, from the surface on one side to the surface on the opposite side. Also assume that we can position a proton anywhere along the...
