Understanding Subscripts and Calculations in Electric Field Equations

[physicstudent15]

When reviewing Electric field I had some confusion as to what the subscripts on [F][/0] and [q][/0] mean. Also what are we calculating here? I know its the electric field but what does this term mean?

You will need to post more context before we can answer your question. Show the whole formula and the definitions of terms that you have.

A friendly tip: you can enter superscripts and subscripts by using the x² and x₂ buttons at the top of the editing window. Highlight the text you want to raise/lower, then click the appropriate button.

Perhaps q₀ denotes a test charge? Then the force on that charge in electric field is denoted as F₀.

OP has been asked for clarification. Until we get it, please don't guess - too much chance of sending the discussion off on counterproductive tangents if you guess wrong.
