A point charge Q is located on the axis of a disc of radius R at a distance b from the plane of the disc (figure). Show that if one-fourth of the electric flux from the charge passes through the disc, then `R=sqrt3b`.

A point charge Q is located on the axis of a disk of radius R at a distance b from the plane of the disk. Show that if one-fourth of the electric flux from the charge passes through the disk, then R = sqrt(3b) .

A point charge Q is located on the axis of a disc of radius R at a distance b from the plane of the disk. If one - fourth of the electric flux from the charge passes through the disk, then R = sqrt(kb) . Find k.

A point charge Q is located on the axis of disc of a radius R at a distance a from the plane of the disc . If one fourth (1//4th) of the flus from the charge passes through the disc, then find the relation between a & R . .

A point charge q is located on the axis of a disc of radius R at a distance b from the plane of the disc as shown in figure 1.295 What should be the radius of the disc if one fourth of the total electric flux form the charge passes through the disc.

A positive point charge Q is placed (on the axis of disc) at a distance of 4 R . Above the centre of a disc of radius R as shown in situation I. the magnitude of electric flux through the disc is (phi) . Now a hemis pherical shell of radius R is placed over the disc. such that it forms a closed surface as shown in situation II. The flux through the curved suface in situation II taking direction of area vector along outward normal as positive is
