You'll need a couple equations and a constant:
$$F =kQ _{1}Q _{2}/d ^{2}$$
k=9.0 x 109 N•m2/C2
That should get you through the first 2 questions.
V=IR, P=VI
$$R _{t}=R _{1}R _{_{2}}R _{3}/(R _{1}+R _{_{2}}+R _{3})$$
Which should answer the next three.

#1 & #2:  As said by mcgyver $$k=9*10^9$$

#3 R=(R1*R2*R3)/(R1*R2+R2*R3+R3*R1)

#4 I=V/R

#5 P=V*I

1) the value is 9*10^9 and unit is Nm^2/C^2
2) the force between them is 23.04*10^(-38) newton
3) the total resistance is 1.66 ohms
4) the current is 5.4021 amperes
5) the total power is 48.444 watts
