Two point charges +1 μC and -1μC are placed at points (0, -0.1m) and (0, +0.1m) respectively in XY plane. Then, choose the correct statement/* from the following :
(a) The electric field at all points on the Y axis has the same direction.
(b) The dipole moment is 0.2 μC-m along +X axis direction.
(c) No work has to be done in bringing a test charge from infinity to the origin.
(d) Electric field at all points on the X axis is along +Y axis.
