The rotation of earth about its axis is………..

A short electric dipole is situated at the origin of coordinate axis with its axis along x-axis and equator along y-axis. It is found that the magnitudes of the electric intensity and electric potential due to the dipole are equal at a point distance r=sqrt(5) m from origin. Find the position vector of the point in first quadrant.
