Answer:
Towards the origin on the positive x-axis.
Explanation:
- For a negatively charged particle the direction electric field lines is always into the charge. So, when a negative charge is placed on the origin then the direction of the electric field lines will be 180° to the positive x-axis, i.e. the field lines will be travelling from infinity towards the origin.
- Contrary to this the positive charges have the direction of electric field lines emerging out from the charge.
