An electron experiences a force equal to its weight, when placed in an electric field. The intensity of the field will be

A

`1.7xx10^(-11)N//C`

B

`5.0xx10^(-11)N//C`

C

`5.5xx10^(-11)N//C`

D

`56N//C`

Text Solution

Verified by Experts

The correct Answer is:
C
Force acting on electron, F = qE
`rArr" "E=(F)/(q)=(mg)/(e)=(9xx10^(-31)xx9.8)/(16xx10^(-19))`
The intensity of electric field, `E=5.5xx10^(-11)"NC"^(-1)`
