What forces do electric fields represent?
They only represent forces between objects of the same charge.
They represent non-contact electrical forces.
They only represent forces between objects with different charges.
They represent forces that are in contact with each other.
What does it mean if electric field lines are close together versus farther apart?
The strength of the electric field is greater.
The electric field is smaller
The electric field is larger.
The strength of the electric field is less.
