Question 3

Based on the arrangement of the electric field lines in the diagram, what are the charges?

Accepted Answer

both charges are the same

Answer

the charges are opposite

Answer

they are neutral; no charge

Question 4

The electric field surrounding a positively charged object is

Accepted Answer

Answer

A.

Answer

B.

Answer

C.

Question 6

Coulomb's law also says if distance increases, then force

Accepted Answer

decreases

Answer

disapears

Answer

destroyed in a heartbeat

Answer

doubles

Question 7

Electric field attractions happen in any charged particles such as positive and negative charges.

Accepted Answer

TRUE

Answer

FALSE

Question 8

The flow of electric force starts at positive and terminates in negative.

Accepted Answer

TRUE

Answer

FALSE

Question 9

Just like magnetism, electric force could be varying as electric field gets wider and bigger. Therefore, this means that the electric force weakens when it is far from the poles.

Accepted Answer

TRUE

Answer

FALSE
