How can you use electric field line representations to model the direction and strength of electric fields for a simple point charge?

• By drawing concentric circles around the charge

• By drawing straight lines radiating outwards from the charge

• By drawing parallel lines around the charge

• By drawing random lines around the charge

How can you use electric field line representations to model the direction and strength of electric fields for pairs of charges?

• By drawing lines that curve from one charge to the other

• By drawing lines that radiate outwards from each charge

• By drawing lines that form a grid pattern between the charges

• By drawing lines that form circles around each charge

How can you use electric field line representations to model the direction and strength of electric fields for dipoles?

• By drawing lines that radiate outwards from each pole

• By drawing lines that form a figure-eight pattern around the dipole

• By drawing lines that curve from the positive to the negative pole

• By drawing lines that form concentric circles around each pole

How can you use electric field line representations to model the direction and strength of electric fields for parallel charged plates?

• By drawing lines that radiate outwards from each plate

• By drawing lines that curve between the plates

• By drawing lines that are parallel and evenly spaced between the plates

• By drawing lines that form concentric circles around each plate

How is the electric field model applied to explain and quantitatively analyze interactions between charged objects?

• All of the above

What is the effect of moving charge in an electric field?

• It creates a magnetic field.

• It remains stationary.

• It experiences a force.

• It loses energy.

How can the effect of moving charge in an electric field be related to potential energy, work, and equipotential lines?
