Heres the thing

Say i was to place 2 small charged spheres into and electric field which points downwards with a strength of 5000 $$N C^-1$$
Can anyone firgure out the force expirienced if the two charges were
+$$2*10^-6$$ and -$$5*10^-6$$???

This belongs in the homework section.

And, yes, a lot of people can figure it out! The question is what have you tried so far?

Um, who said this was homework, practical expiriment perhaps?

Sorry, for sounding like that anyway...

I tried using $$\frac{F=k q_1 q_2}{r^2}$$

But without the distance i had no idea
and i also dont know how i should put the downwards force into the equation, should i use a vector?
