Two particles A and B having oposite charges 2.0×10−6C and −2.0×10−6C, are placed at a separation of 1.0 cm. (a) Write down te electric diple moment of this pair. (b) calculate the electric field at a Point on the axis of the dipole 1.0 m away from the centre. (c) Calculat the electric field at a point on the perpendicular bisector of the dipole and 1.0 m away from the centre.
