Electric Field Lines For Isolated Negative Charge

While we use blue arrows to represent the magnitude and direction of the electric field we use green lines to represent places where the electric potential is constant.

Electric field lines for isolated negative charge.

B sketch the electric field pattern around an isolated negative point charge of magnitude 2q. Electric field lines radiate out from a positive charge and terminate on negative charges. Two point charges are a small distance apart. In fact electric fields originate at a positive charge and terminate at a negative charge.

The properties of electric field lines for any charge distribution are that. Since the electric field lines point radially away from the charge they are perpendicular to the equipotential lines. Electric field lines radiate out from a positive charge and terminate on negative charges. For a positive charge these lines emanate radially outward from the charge.

The electric field around a charged object is represented using imaginary lines of forces called electric field lines. Electric field of point charges also field lines never cross each other. In contrast for a negative charge the lines are directed inwards towards the charge. The number of field lines leaving a positive charge or entering a negative charge is proportional to the magnitude of the charge.

Because positive charges repel each other the electric field around an isolated positive charge is oriented radially outward. Electric field lines never cross each other. When they are represented by lines of force or field lines electric fields are depicted as starting on positive charges and terminating on negative charges. A sketch the electric field lines for the two if one has a charge four times that of the other and both charges are positive.

Measuring e using a test charge. Electric field lines are most dense around objects with the greatest amount of charge. A sketch the electric field lines around an isolated point charge q 0.
