Question

An electron starts at rest in a uniform electric field. Fill in the blanks: the electron will move towards___ electric potential, and the electric potential energy of the electron in the field will____

a) higher,increace
b)lower,increase
c)higher,dcrease
d)lower,decrease

Answer 1

Electrons will always try to move towards the lower potential. The kinetic energy will increase, so the electric potential energy of the electron in the field will decrease.
