The electric field in a region is given ...

The electric field in a region is given by `E=ahati+bhatj`. Hence as and b are constants. Find the net flux passing through a square area of side `l` parallel to y-z plane.

A

`al^3`

B

`al^2`

C

`al^4`

D

`al`

Text Solution

Verified by Experts

The correct Answer is:
B
A square area of side l parallel to y-z plane in vector from can be written as
`S=l^2hati`
Given, `E=ahati+bhatj`
`:.` Electric flux passing through the given area will be
`phi=E.S`
`=(ahati+bhatj).(l^2hati)`
`=al^2`
