Which graph best represents the relationship between the strength of an electric field and distance from a point charge?
Based on the arrangement of the electric field lines in the diagram, what are the charges?
both charges are positive
the charges are opposite
both charges are negative
cannot tell based on the figure
Which statement best describes the electric fields in the image?
The charges are neutral.
Both charges are negative, so the field lines are alike.
The field lines move toward a positive charge and away from a negative charge.
The field lines move away from a positive charge and toward a negative charge.

in a gravitational field
in the space surrounding a charged object
outside of a magnetic field

around a magnet
Which of the following features of an electrostatic line of force is NOT correct?
It is an imaginary line which a positive charge would describe if it is free to move
The tangent drawn at any point on a curved line of force shows the direction of the electric field intensity at that point
It is sometimes curved
It can cross another line of force in a region of intense electric field

pointing towards the charge
curving
further
closer together
The electric field is uniform between two oppositely charged metal plates. This means that
