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?
The Attempt at a Solution
I tried evaluating the graph and seeing as it is a straight line for both the x and y components of the E field i was thinking i could get a partial derivative
I think this is where i went wrong.
anyhow, I went on to find the magnitude and direction of the E field
the next step given the force on an electron as F=qE
finding this for the separate components in vector notation give q=1.6*10^-19C
so F=(1.6*10^-19C)*[(1250N/Ci), (-250N/Cj)]
it is not the right answer so my understanding is failing at a point
