Why do electric field lines point away from positive charges and towards negative charges?
Since like charges repel and unlike charges attract, the electric field of a positive charge would point away from it and the other way around for a negative charge.
Why are field lines outward from positive charge?
The direction of the force that is exerted on a negative charge is opposite that which is exerted on a positive charge. Because positive charges repel each other, the electric field around an isolated positive charge is oriented radially outward.
What happens when a positive charge and negative charge meet?
If a positive charge and a negative charge interact, their forces act in the same direction, from the positive to the negative charge. As a result opposite charges attract each other: The electric field and resulting forces produced by two electrical charges of opposite polarity.
Where do electric field lines from a positive charge go when there is no negative charge brought near for them to terminate?
Field lines should always point away from positive charges and towards negative charge.
What happens when a positive and a positive meet?
That is, a positively charged object will exert a repulsive force upon a second positively charged object. This repulsive force will push the two objects apart.
Why do electric field lines explain why like charges repel and opposite charges attract?
When charged particles are close enough to exert force on each other, their electric fields interact. The lines of force bend together when particles with different charges attract each other. The lines bend apart when particles with like charges repel each other.
When a positively charged ion moves in the same direction as the electric field How does the electric potential energy change?
When work is done on a positive test charge to move it from one location to another, potential energy increases and electric potential increases.
