Will two point charges, each with a charge of +1 Coulomb and separated by a distance of 1 meter, attract or repel?

Like charges attract - unlike repel.
The force of two charges of +1C each at a distance of 1 m would be approximately 9x10^9 N and repulsive.
This is evident through Coulomb's law where the Force is proportional to the product of charges.
As charges can be negative or positive, the product can have either a (-) or a (+) resultant.
Thus if the product resultant is negative the force is attractive and if it is positive the force is repulsive.
