A constant Electric field →E=2^i exists in space. The electric flux through a square surface of side 2m with its surface tilted 600 from the y axis is4Nm2C.
True
ϕ=→E.→A
You can take either →E in the direction of area vector →A or vice versa, it is the same thing and will give you same flux. It just looks different.
Now →E in the direction of →A
ϕ=EAcos600=4.22=4Nm2C.
