Two points P and Q which is at same distance r from the dipole, but P is on axial line and Q is on equatorial line. the ratio of electric field intensity at P and Q is

If E_(a) be the electric field strength of a short dipole at a point on its axial line and E_(e) that on the equatorial line at the same distance, then

In th electric potential on the axis of an electric dipole at a distance 'r' from it is V, then the potential at a point on its equatorial line at the same distance away frornt it will be

If E_(a) be the electric field strength of a short dipole at a point on its axial line and E_(e ) that on the equatorial line at the same distance, then

If the intensity of electric field at a distance x from the centre in axial position of small electric dipole is equal to the intensity at a distance y in equatorial position, then

The electric field due to a short dipole at a distance r, on the axial line, from its mid point is the same as electric field at a distance r^(') on the equatorial line, from its mid point.Determine the ratio r//r' .

A point Q lies on the perpendicular bisector of an electrical dipole of dipole moment p , If the distance of Q from the dipole is r (much larger than the size of the dipole), then electric field at Q is proportional to

A point source emits sound equally in all directions in a non-absorbing medium. Two point P and Q are at distance of 2 m and 3 m respectively from the source. The ratio of the intensities of the wave at P and Q is :

Show that the relation R on the set A of points in a plane, given by R={(P ,\ Q): Distance of the point P from the origin is same as the distance of the point Q from the origin}, is an equivalence relation. Further show that the set of all points related to a point P!=(0,\ 0) is the circle passing through P with origin as centre.

Show that the relation R on the set A of points in a plane, given by R={(P ,\ Q): Distance of the point P from the origin is same as the distance of the point Q from the origin}, is an equivalence relation. Further show that the set of all points related to a point P!=(0,\ 0) is the circle passing through P with origin as centre.

Two equal charges q of opposite sign separated by a distance 2a constitute an electric dipole of dipole moment p . If P is a point at a distance r from the centre of the dipole and the line joining the centre of the dipole to this point makes an angle theta with the axis of the dipole, then then potential at P is given by (r gt gt 2a) where (p = 2 qa)
