Hello,

E = 5i + 2j N/C (Given)

Area of square = 2 m^2 (Given)

Using Gauss's Law, we have, Electric flux = Electric field * Area

Flux = E * A = E * A * cos theta

Flux = (5i + 2j) * 2 * cos 0 [In y-z plane, theta will be 0]

= 5 * 2 = 10 [Also in y-z plane, electric field will only have 'i' component and j' component will be zero because it is parallel to the y-z plane]

Flux = 10 Weber (Answer)
