Choose the statement(s) that is/are true about an electric field. (i) The electric potential decreases in the direction of an electric field. (ii) A positive charge experiences a force in the direction of an electric field. (iii) An electron placed in an electric field will move opposite to the direction of the field.

Respuesta :

Answer:

A positive charge experiences a force in the direction of an electric field.

Explanation:

Electric field is defined as the electric force acting per unit positive charge. Mathematically, it is given by :

[tex]E=\dfrac{F}{q}[/tex]

We know that like charges repel each other while unlike charges attract each other. The direction of electric field is in the direction of electric force. For a positive charge the field lines are outwards and for a negative charge the electric field lines are inwards.

So, the correct option is (b) "A positive charge experiences a force in the direction of an electric field".
