True since coulomb's law states that There is electric force between like charges or opposite charges. The negative sign only shows the nature of the force.
What is the coulombs law ?
coulombs formula is given by
[tex]F= \dfrac{K\times q_{1} \times q_{2}}{r^{2} }[/tex]
Now it states that if two charged particles are separated by the distance r and having same or opposite charge will attract or repel each other.
The intensity of the force depend upon the distance and the nature of the charge.
