Would the electron released from rest move to a region of higher electrical potential or lower electrical potential

he electron moves in the direction of a greater electric potential

Explanation:

Electric potential and electric field are related

          V = -∫ E .ds

t

he electric force is related to the electric field

           F = q E

           F = q (-dV / ds)

since the electron has charge a = 1.6 1019 C

           F = e dv / ds

therefore the electron moves in the direction of a greater electric potential

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
