At the point of the electric field located in the middle between two opposite and equal in modulus charges 1) the intensity is zero, and the resulting potential is twice the field potential of each charge 2) the potential is zero, and the resulting intensity is twice the field strength of each charge 3) the resulting potential and intensity is twice potential and field strength of each charge 4) the resulting strength and potential are equal to zero
Electric field strength at a distance r from charge q:
E = k * q / r ^ 2;
For a positive charge, E is directed from charge, for a negative charge to charge. This means that at a point in the middle between the charges, their intensities will be directed in one direction (from the positive charge) and the resulting intensity will double;
The potential of the electric field at a distance r from the charge q:
φ = k * q / r;
Since the sign of the potential depends on the sign of the charge, the resulting potential at a point in the middle between the charges will be zero.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
