Electric field intensity due to an infinite plane sheet of charge is

• σ/εo

• q/2εo

• σ/2εo

• q/εo

Electric flux lines due to an infinite sheet of charge is

• converging

• radial

• uniform and perpendicular to the sheet

• uniform and parallel to the sheet

Total flux across a closed surface enclosing charge is independent of

• shape of the closed surface

• volume of the enclosure

• actual spatial argument of charges within the surface

• all the above

The total electric flux over any closed surface is

• εo

• q2/εo

• εo/q

• q/εo

Electric intensity due to an infinitely long plane sheet of a conductor at a point close to its surface is

• independent of r

• proportional to 1/r2

• proportional to 1/r

• inversely proportional to 1/r

Electric intensity at any point between two identical conducting plates connected to a DC supply source is

• directly proportional to distance between the plates

• inversely proportional to the square of the distance between the plates

• uniform directed from positive to negative plates

• inversely proportional to the distance between the plates

A Gaussian sphere closes an electric dipole within it. Then the total flux through the sphere is

• half that due to a single charge

• double due to a single charge

• zero

• dependent of the position of the dipole

The total electric flux through a closed surface depends

• on the location of the charge only

• on the shape of the closed surface only

• on the value of the net charge only

• both on the location of the charge and the shape of the surface
