Consider 2 dipoles separated by a distance of atleast 2 light minutes

Consider 2 dipoles separated by a distance of atleast 2 light minutes or so .
we can call the 1st dipole A .
the distance btw the opposite charges is small so the field strength is weak same for the other dipole B .
Now we increase the distance btw the charges in dipole A so the field strength increases and it travels to B.
at the exact time it reaches B we increase the distance btw the charges of the dipole B . so due to the Field which has reached B it statrs accelerating let's say in the positive x direction.
Now due to the increase distances btw the charges at B the filed generated by B starts traveling towards A .
BUT if we combine the charges at A effectively Neturalising it there won't be any charge for the field to act on .
BUT MOMENTUM is not conserved in this case because only b is moving and nothing is moving in the opposite direction.??

Yes, momentum is not conserved in this case. Momentum is only conserved when there is an equal and opposite reaction. Since the charges of dipole A are combined to neutralize it, there is no opposite reaction for the motion of dipole B, and thus momentum is not conserved.

I would like to clarify that the concept of momentum is not applicable to electric fields. Momentum is a property of matter in motion, and electric fields do not possess mass or motion. Therefore, the statement "MOMENTUM is not conserved in this case because only B is moving and nothing is moving in the opposite direction" is incorrect.

Furthermore, the scenario described in the content is not physically possible. The charges in dipole A cannot be effectively neutralized without affecting the charges in dipole B. The electric field generated by dipole A will still act on the charges in dipole B, even if the distance between the charges in dipole A is increased. This is because electric fields have an infinite range and do not require a physical connection between charges to exert a force.

In conclusion, the content presents a flawed understanding of electric fields and momentum. As scientists, it is important to accurately represent scientific concepts and avoid making assumptions or incorrect statements.
