Electric Field Around Two Negative Charges

Electric field around two like charges both negative we can use the fact that the direction of the force is reversedfor a test charge if you change the sign of the charge that isinfluencing it.

Electric field around 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. Sketch the electric field around the following arrangements of small charged objects. Two positive charges of equal magnitude. An electric dipole one positive and one negative charge of equal magnitude.

Note that the electric field is defined for a positive test charge q so that the field lines point away from a positive charge and toward a negative charge. Electric field lines never cross each other. If we change to the case where both charges arenegative we get the following result. Electric field lines always extend from a positively charged object to a negatively charged object from a positively charged object to infinity or from infinity to a negatively charged object.

Electric field lines are most dense around objects with the greatest amount of charge. Like charges repel each other and unlike charges attract each other. See figure 2 see figure 2 the electric field strength is exactly proportional to the number of field lines per unit area since the magnitude of the electric field for a point charge is latex e k frac q r 2 latex and area is proportional to r 2. An object with an absence of net charge is referred to as neutral.

An electric charge is a property of matter that causes two objects to attract or repel depending on their charges positive or negative. Charges of different magnitudes. Positive and negative commonly carried by protons and electrons respectively. An isolated negative charge.

An isolated positive charge.
