Explanation / Answer

Answer for question 3

Electric flux through the given cube placed in the given electric field will be zero

Explaination:

Since electric field is in the x direction hence the surfaces perpendicular to y axis and z axis will have area vectors perpendicular to the x axis

Flux depend on dot product of electric field and area vector hence flux through 4 surfaces will be zero.

Since electric field is not varying , it is constant so for other two faces even perpendicular to x axis will also be zero as the flux which enters the cube is same as flux leaving the cube.

So net flux will always be zero as the elctric field is constant.
