Question:

Force charges +q,-q,+q,-q placed at 4 corners of a square of sides 'a'.Calculate the resultant force on +Q charge at the intersection of 2 diagonals.

CONTACT AND NON CONTACT FORCES:

Forces are of two types 1) contact forces 2) .non contact forces. Tension ,friction, normal reaction, elastic an collision forces are contact forces. Gravitational and electromagnetic forces are non contact type. Electrostatic force is a part of electromagnetic force. Non contact forces act even in vacuum. These forces arises due to interaction. Electrostatic force is a strong , large range force. This force depends upon the medium in which charges are kept.
