An electron enters between two horizontal plates separated by `2 mm` and having a potential difference of `1000V`. The force on electron is

A

`8 xx10^(-12)N`

B

`8 xx10^(-14)N`

C

`8 xx10^(9)N`

D

`8 xx10^(14)N`

Text Solution

Verified by Experts

The correct Answer is:
B
Force (F) = qE = `q(V/d) = 1.6 xx10^(-19) xx1000/(2xx10^(-3))`
`=0.8 xx10^(-13)= 8 xx10^(-14) N`
