INTERCAPACITANCE BETWEEN TWO CHARGES LOCATED IN THE DIFFERENT ENVIRONMENTS

It is investigated the dependence of intercapacitance between two point charges located in different environments on the relative position of border. The image method is used. It is considered two cases: the charges is located at line which is perpendicular to the border and the charges is located at
line which is not perpendicular to the border. The result show that in both cases the capacitance is increased with displacement the border.
