Question

Which of the following statements about electric field lines associated with electric charges is false? Electric field lines can be either straight or curved. Electric field lines can form closed loops. Electric field lines begin on positive chares and end on negative charges. Electric field lines can never intersect with one another.

Answer 1

The false statement is 'Electric field lines form closed loops'.

Step-by-step explanation:

• Electric field lines originate from positive end and terminates at negative end,i.e., field lines are inward in direction to the negative charges and outward from the positive charges.
• These lines when close together represents high intensity and when far apart shows low intensity of the field.
• These lines do not intersect, as the tangent drawn on these lines provides us with the field direction and intersection of these lines means two field directions which is not possible.
• These lines unlike magnetic field lines do not form closed loops as they do not turn around but originate at positive end and terminates at negative end which ensures no loop formation.
