By Coulomb's law, we will see that the force is 898.8 N, and the charges repel each other.
Coulomb's law says that the force is:
[tex]F = k*\frac{q_1*q_2}{R^2}[/tex]
Where k is a constant, the q's are the charges of each particle, and R is the distance between the particles.
We have:
Then the force is:
[tex]F = 8.988*10^9*\frac{1*10^{-3}*10^{-2}}{(10)^2} N = 898.8 N[/tex]
And because both particles have positive charge, the charges repel each other.
