PHY 102 ELECTROSTATICS Objective Question
Take CBT

Question

According to the document, why do electric field lines never cross?
Options
A Because they always form closed loops.
B Because a charge placed at the intersection would be 'confused' about which direction to move.
Correct Answer
C Because electric field lines always run parallel to each other.
D Because they originate from positive charges and terminate on negative charges.
Correct Answer

Option B is the correct answer.

Detailed Explanation

The document states on page 10, 'This is also why field lines do not cross. If they do, that would mean that a charge would be 'confused' as there are two or more directions in which it can move.' This directly addresses the reason.

Hint

Think about what an electric field line represents regarding the direction of force on a charge.
