Question

choose the most correct answer: electric field lines originate from the *
center of the electric field
the charge with greatest strength
the negative charge
the positive charge

choose the most correct answer: if the sign of the electric field is the same as the charge
they attract
they repel
they increase
they are equal

Explanation:

• First question: Electric field lines are a visual representation. By convention, they originate from positive charges and terminate on negative charges. This is a fundamental property in the study of electric fields.
• Second question: The basic principle of electrostatics states that like charges repel each other. If the sign of the electric field (which is determined by the source charge) is the same as the test charge, they will repel. For example, a positive test charge in a field created by a positive source charge will experience a repulsive force.

Answer:

• First question: The positive charge
• Second question: They repel
