Answer:
(A) Acceleration will be

(b) Time taken will be

(c) Force will be
Step-by-step explanation:
We have given that electron starts from rest so initial velocity u = 0 m/sec
Final velocity

Mass of electron

Distance traveled by electron

From third equation of motion we know that

(a) So


(b) From first equation of motion we know that v = u+at
So


(c) From newton's law we know that force
