Explanation:
A charge alters the space around it. This alteration of space is called the electric field. It is also defined as the electric force acting on a charged particle per unit test charge. It is given by :
[tex]E=\dfrac{F}{q}[/tex]
Where
F is the electric force, [tex]F=\dfrac{kq_1q_2}{r^2}[/tex]
The direction of electric field is in the direction of electric force. For a positive charge, the direction of electric field lines are outwards and for a negative charge, the direction of field lines are inwards.
Hence, the correct option is (c) "electric field".
