An electron enters a region where electrostatic field is `20N//C` and magnetic field is `5T`. If electron passes undeflected through the region, then velocity of electron will be

A

`0.25 ms^(-1)`

B

`2 ms^(-1)`

C

`4 ms^(-1)`

D

`8 ms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
