Physics question for practice quiz? Please Help!!!?

Particle (a) has mass m and charge +q and is thus attracted to particle (b) with mass 2m and charge -2q. Which particle is more attracted toward the other, and by how much? 
a==Particle (a) by 2x 
b==Particle (a) by 4x 
c==Particle (b) by 2x 
d==Particle (b) by 4x 
e==Neither, they are attracted by the same amount 
f==Neither, their charges cancel and they are not attracted 

I'm thinking the larger particle is more attracted to the smaller particle because it has more surface area to attract the smaller particle and because the larger particle is twice as negatively charged so it would be twice as attracted to the positive charge?? So maybe c or d? 

Thanks
