Homework Statement



I have physics homework and i don't quite seem to understand the question:
Two objects ( X and Y ) are placed at a distance of .800m from each other. The charge on X is 6.65000x10^-6 C and Y is 7.73000x10^-6. What is the value of electrical force (in Newtons) between the two objects? Answer accurate to the fourth decimal place.

Homework Equations



i think the equation is F=kxQ1xQ2/d^2, but don't know how to solve for Q1 or Q2..and is K 9.0x10^9?
ive tried reading the info. they provide us over and over but still don't seem to get how to solve it

The Attempt at a Solution


:cry: i know I am a noob but please help lol
thank you

Q1 and Q2 are the charges on the objects, d is the distance between the objects, and k is Coulomb's constant
 
but the thing is i don't know where to start..

They give you all of those values, except for k which you can look up. Unless I'm missing something, all you have to do is plug them into the equation to get the force.
 
how do i get values of k, q1, and q2 in units of Coulomb?
oh wait they give it to us in C
 
oh ok..let me try that..ive tried plugging in over and over..but couldn't get the answer..
