A positively charged particle is placed near a negatively charged particle. What is the direction of the electric force between the two particles?
Opposite charges attract. A positive particle near a negative one is pulled towards it, along the straight line joining them. So the force on the positive particle points from it towards the negative particle.
The force is not zero, because charges always exert a force on each other, and its direction is easy to work out from the signs of the charges.
The option saying the force runs from the negative to the positive particle describes the pull on the negative particle, not the usual direction used for the pair.
