An electron enters in high potential region `V_(2)` from lower potential region `V_(1)` then its velocity

A

will increases

B

will change in direction but not in magnitude

C

bo change in direction of filed

D

no change in direction perpendicular to field

Text Solution

Verified by Experts

The correct Answer is:
A

Electron is moving in opposite direction of field so field will produce an accelerating effect on electron.
