find the force and force direction of a 1.0x10^6 C charge that is 2cm North and 3cm East of a 2x10^6 C charge

Use Coulomb's law to get the force.
F = k Q1 Q2/R^2
The Q's are the two charges. R is the distance between the charges, which is sqrt [2^2 + 3^2]= sqrt13 cm
The direction of the force is along the vector from the 2*10^6 charge to the 1*10^6 charge, since it is a repulsive force.
