The electric field intensity at all points in space is given by `vec(E) = sqrt(3) hat (i) - hat (j)` volts/metre. A square frame LMNO of side 1 metre is shown in figure. The point N lies in x-y plane. The initial angle between line ON and x-axis is `theta = 60^(@)`
The magnitude of electric flux through area enclosed in square frame LMNO is -
A. 0 volt metre
B. 1 volt metre
C. 2 volt metre
D. 4 volt metre
