An electric dipole consists of a particle with a charge of +6 * 10^-6 C at the origin and a particle with a charge of -6*10^-6 C on the x axis at x = 3 *10^-3 m.The direction of the electric field due to the dipole at points on the x axis is: A)in the positive x direction B)in the negative x direction C)in the positive y direction D)in the negative y direction E)in the positive x direction between the charges and in the negative x direction elsewhere

On the x-axis, the electric field due to the positive charge at the origin will be in the negative x-direction (towards the negative charge). Similarly, the electric field due to the negative charge will be in the positive x-direction (away from the negative charge). Therefore, between the charges, the net electric field will be in the positive x-direction, and outside the charges, the net electric field will be in the negative x-direction. Therefore, the correct choice is E, where the electric field is in the positive x-direction between the charges and in the negative x-direction elsewhere.
