A point charge `q` is placed at a distance `d` form the center of circular disc of radius `R`. Find electric flux through the disc due to that charge

A point charge q is placed at a distance a//2 directly above the centre of a square of side a . The electric flux through the square is

A point charge Q is placed at the centre of circular disc of radius r . Calculate the electric flux associated with circular disc.

A position charge Q is placed at a distance of 4R above the centre of a disc of radius R. The magnitude of flux through the disc is phi . Now a hemispherical shell of radius R is placed over the disc such that it forms a closed surface. The flux through the curved surface (taking direction of area vector along outward normal as positive), is -

a point charge q is placed at the centre of a cylinder of length L and radius R the electric flux through the curved surface of the cylinder is

A charge q is placed at the centre of a cylinder of radius R and length 2R. Then electric flux through the curved surface of the cylinder is

Point charge Q is placed at point P in the plane of circular face of sphere. The electric flux passing through the spherical part shown in the figure is:-

A point charge q is placed at a distance (a)/(2) directly above the centre of a horizontal square of side 'a' and another point charge -q is placed at a distance 'a' directly below one of its (the square's) corners. The electric flux through the square is :
