The `(e)/(m)` value of electron is

A

`9.76xx10^(11)C(kg)^(-1)`

B

`6.6xx10^(27)C(kg)^(-1)`

C

`3.52xx10^(11)C(kg)^(-1)`

D

`1.76xx10^(11)C(kg)^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
D
The charge on electron is given by, `e=1.6xx10^(-19)C`
and mass off an electron is `m=9.1xx10^(-31)kg`
Hence, value of e/m is `=(1.6xx10^(-19))/(9.1xx10^(-31))=1.76xx10^(11)C(kg)^(-1)`.
