Explain why electric field lines never cross each other.

• Because they represent the path of a single charge

• Because each point in space can only have one direction of the electric field

• Because they are imaginary lines

• Because they are always parallel

A charged particle is placed in a uniform electric field. Describe the motion of the particle.

• It will move in a circular path

• It will move in a straight line along the field direction

• It will remain stationary

• It will move in a zigzag pattern

What is the relationship between electric field strength and the spacing of electric field lines?

• Closer lines indicate a weaker field

• Closer lines indicate a stronger field

• Spacing does not affect field strength

• Wider lines indicate a stronger field

If two equipotential surfaces are closer together, what does this indicate about the electric field strength between them?

• The field is weaker

• The field is stronger

• The field is uniform

• The field is zero

Discuss how a Van de Graaff generator demonstrates the concept of electric fields.

• It shows how charges can be stored

• It demonstrates the movement of charges along field lines

• It illustrates the concept of potential difference

• It shows the conversion of mechanical energy to electrical energy
