Electric field is a space or region around the given charge where other test charge experiences a force of attraction or repulsion. And Electric field intensity is the vector quantity directed towards the force acting on the charge. (According to me the intensity or no. of Electric field lines passing through a charged body)

Actually coulombs law is a similar very similar to Newton's law of gravitation which says that the force of attraction between two bodies is the product of their charges in Newton's law of radiation will take masses of two bodies but you are in coulombs law will take the mask charges of June two bodies and inversely proportional to square of the distance between them so it will be directly proportional to Q1 and Q2 and half will be inversely proportional to 1 by a square if you remove the professionally constant and if you join the both equation then will get that is equal to K Q1 Q2 by R squared in which day is nothing but the specific permittivity that is permittivity of free space
