Question
An electron is projected as in figure with kinetic energy K, at an angle θ = 45o between two charged plates. The magnitude of the electric field so that the electron just fails to strike the upper plate, should be greater than :
Options
A.
B.
C.
D.Infinite
Solution
If particle will lose KE (in that direction) against work done by electric field 
= qEd
⇒ E =
= qEd⇒ E =
