Q-1
A point charge q is located a distance d from an infinite
plane. Determine the electric flux through the
plane due to the point charge.
Q-2
A point charge q is located a very small distance from the center of a very
large square on the line perpendicular to the square and
going through its center. Determine the approximate
electric flux through the square due to the point
charge.
Q-3
The line ag is a diagonal of a cube(in below figure). A
point charge q is located on the extension of line ag ,
very close to vertex a of the cube. Determine the electric
flux through each of the sides of the cube that meet
at the point a.

11) q/2ε0
(as the plate is infinite it covers almost half the solid angle of 4Î )
2) q/6ε0
(cmplete the square into a cube and proceed)
3) q/24ε0 (through each if it s not touching the cube)
(make another gaussian cube of length twice that of the cube)
