Answer 1

Question:- Explain how you would know the strength of electric force by looking at the electric lines of force.

Answer:- The closeness of the lines is directly related to the strength of the electric field. A test charge placed anywhere will feel a force in the direction of the field line; this force will have a strength proportional to the density of the lines (being greater near the charge, for example).
