If `vecE = (E_(0)X)/a hati(x-mt)` then flux through the shaded area is:

A

`E_(0)a^(2)`

B

Zero

C

`E_(0)a^(3)`

D

`-E_(0)a^(3)`

Text Solution

Verified by Experts

The correct Answer is:
A
`varphi =int vecE. dvecA`
`=int (E_(0)a)/a dA`
`=E_(0) int dA = E_(0)a^(2)`
`(pi J_(0))/R = int_(0)^(R ) dr`
`(pi J_(0))/(Y) =(R^(y))/(pi) = pi R^(3) J_(0) J_(0)4R`
