HELP PLEASE all charged objects create an electric field around them. what two factors determine the strength of two electric fields upon the charged objects creating them?

1) how charged the object creating the field is and the density of the charged objects

2) how charged the object creating the field is and weather the objects are positively or negatively charged

3) how charged the object creating the field is and the mass of the two charged objects

4) how charged the object creating the field is and the distance between the two charged objects
