Electric field between two negative charges.

An electric field is a region of space around an electrically charged particle or object in which an electric charge would feel force. Because equal positive and negative charges makes no sense unless you have 4 charges 2 plus 2 minus. A useful means of visually representing the vector nature of an electric field is through the use of electric field lines of force. Because we re dividing a vector quantity by a scalar quantity charge.

So the electric field at that point is going to be k times whatever charge it is divided by 2 meters so divided by. And the formula looks like this. You can estimate the electric field created by a point charge with below electric field equation. The field is stronger between the charges.

So this is the center to center distance. Think about it i want the net electric field halfway between the two charges so the r that i care about in this electric field formula is the distance from the charge to the point where i want to determine the electric field and in that case this is three meters. So coulomb s law told us that the force between two charges is going to be equal to coulomb s constant times and in this case the first charge is big q. Furthermore at a great distance from two like charges the field becomes identical to the field from a single larger charge figure 5b shows the electric field of two unlike charges.

If you mean midway between two equal charges c is correct. In that region the fields from each charge are in the same direction and so their strengths add. A true if you mean midway between two equal charges c is correct. A lot of people wanna put in six but that s not what i want.

Good grammar is your friend. We ll call that r. For example if you place a positive test charge in an electric field and the charge moves to the right you know the direction of the electric field in that region points to the right. A pattern of several lines are drawn that extend between infinity and the source charge or from a source charge to a second nearby charge.

Do you mean two charges equal in magnitude but opposite in sign. E k q r. An electric charge is a property of matter that causes two objects to attract or repel depending on their charges positive or negative.
