Question

an electron enters in higher potential region V2 from lower potential region V1 then its velocity will​

Answer 1

Answer:

decreases

Explanation:

by conservation of energy

eV2=0.5 m$v_{1}$^2

eV1=0.5m$v_{2}$

thus by seeing eqn we know it

method2-

if pd is developed the there would be resitance which is opposing the motion of electron hence the speed would decrease
