PLEASE HELP!! I HAVE A TEST TOMORROW!!

i just posted this problem but a very important drawing was left out!

if Q=30 uC, q=5.0 uC, and d=30cm, what is the magnitude of the electrostatic force on q in N?

(Ke= 8.99 x 10^9 Nm^2/C^2)

(uC= micro coulombs)

(u= 10^-6)

d 2d

O<--->O<--------->O

Q q 2Q

a. 15

b. 23

c. zero

d. 7.5

e 38

i know coulomb's law but i don't know how to apply it to this problem
