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

A

`4.36xx10^(-11)N//C`

B

`5.573xx10^(-11)N//C`

C

`6.67xx10^(-11)N//C`

D

`9.86xx10^(-11)N//C`

Text Solution

Verified by Experts

The correct Answer is:
B
`F=mg=eE`
`therefore" "E=(mg)/e=(9.1xx10^(-31)xx9.8)/(1.6xx10^(-19))`
`=5.573xx10^(-11)N//C`
