3. A 10 cm by 10 cm square flat plate is located 5 cm from a point charge of 2 nC.The point charge is at the origin of a Cartesian

coordinate frame. The surface of the square plate is in the xz plane and the y axis passes through the middle of the square plate. The edges of the plate are parallel to the x and z axes. The square plate is located at y = +5 cm. The square plate extends from z = -5 cm to z = +5 c mand x = -5 cm to x = +5 cm. Calculate the total electric flux passing through the plate due to the point charge.
