1. The problem statement, all variables and given/known data List the 4 properties and characteristics of electric field lines. 2. Relevant equations I was not able to get them all and the ones that I did get I am confused that if it is really a characteristic or a property 3. The attempt at a solution 1. Characteristic: The closer the field lines the greater the intensity (closer field lines have are greater in density) 2. Property: When there is more than 1 source; the electric field strength is the vector sum of both sources ( the electric field strength is a vector quantity so it has a direction). 3. Characteristic: In the presence of a positive charge (inside electric field line), the field lines would radiate straight out (just as a positive test charge would be pushed out). 4. Characteristic: At every point on the electric field line (since the field lines are often curved), the direction of the field is tangent to the line. 5. Property: the electric field strength between two parallel plates is the quotient of voltage over charge(q1 causing the electric field) while the electric field strength near a point charge is the quotient of the electric force over the charge(q1 that is causing the electric field) thanks for your responses.
