Electric field is a vector quantity whose direction is defined as the direction that a positive test charge would be pushed when placed in the field.
Electric field lines around a negative charge.
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.
Field lines of a single position charge points radially outwards while that of a negative charge are radially inwards as shown below in the figure.
Field lines around the system of two positive.
Electric field lines never cross each other.
Electric field lines are most dense around objects with the greatest amount of charge.
An electric field is a region of space around an electrically charged particle or object in which an electric charge would feel force.
For the field lines to either start or end at infinity a single charge must be used.
The start point of the field lines is at the positive charge and end at the negative charge.
Thus the electric field direction about a positive source charge is always directed away from the positive source.
Field lines must begin on positive charges and terminate on negative charges or at infinity in the hypothetical case of isolated charges.
An electric field line is in general a curve drawn in such a way that the tangent to it ateach point is the direction of net field at that point.
The properties of electric field lines for any charge distribution are that.
And the electric field direction about a negative source charge is always.
The lines are defined as pointing radially outward away from a positive charge or radially inward.
An electric field is a vector quantity and can be visualized as arrows going toward or away from charges.
