The electric components in the figure are `E_(x)=alphax^(1//2) ,E_(y)=0,E_(z)=0` where `alpha=800N//m^(2)` if `a=0.1m` is the side of cube then the charge with in the cube is

A

`9.27xx10^(-12)C`

B

`9.27xx10^(12)C`

C

`6.97xx10^(-12)C`

D

`6.97xx10^(12)C`

Text Solution

Verified by Experts

The correct Answer is:
A
By Gauss's law, `phi=q/epsilon_(0)`
`or" " q=phiepsilon_(0)=1.05xx8.854xx10^(-12)C=9.27xx10^(-12)C`
