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 `I` parallel to y-z plane.

Options

A. `a^(2)l^(2)`
B. `al^(2)`
C. `b^(2)l^(2)`
D. `bl^(2)`

Answer

B

Explanation

A square area of side l parallel t Y-Z plane in vector form can be written as `S=l^(2)hati`
Given, `" "E=ahati+bhatj`
`therefore" Electric flux passing through the given area will be "`
`phi_(E)=E.S=(ahati+bhatj).(l^(2)hati)=al^(2)`
