no idea.. maybe other E field is -0.3 to cancel it out?

An electric field is a region in space where an electric charge experiences a force. It is represented by a vector quantity and is created by the presence of other electric charges.
The strength of an electric field is determined by the magnitude and direction of the electric charge and the distance between the charges. The electric field is calculated using Coulomb's law, which states that the force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
The unit of electric field is Newtons per Coulomb (N/C) in SI units. In other systems of units, it can also be expressed as volts per meter (V/m).
Electric charges interact with an electric field by exerting a force on each other. Positive charges are attracted to negative charges, while like charges repel each other. The strength and direction of the force depend on the magnitude and direction of the electric field.
Electric potential is a scalar quantity that represents the potential energy per unit charge at a specific point in an electric field. It is measured in volts (V). On the other hand, electric field is a vector quantity that represents the force per unit charge exerted by the electric field on a charge. It is measured in N/C or V/m.
