Two point charges +q and q are held fixed at (d, o) and (d, o) respectively of a x-y coordinate system. Then

The electric field E at all points on the x-axis has the same direction

Electric field at all points on y-axis

Work has to be done in bringing a test charge from ( to the origin

The dipole moment is 2 qd along the x-axis

Two equal point charges are fixed at x = -a and x= +a on the x-axis. Another point charge Q is placed at the origin. The change in the electrical potential energy of Q, when it is displaced by a small distance x along the x-axis, is approximately proportional to
