! i have a physics exam tomorrow and i just can't wrap my head around this one!

three charged particles lie on the same straight line. their charges are equal:

qa=qb=qc=0.5 microcoulombs

charged particle b is in between particles a and c, in the middle. what is the intensity of the electrostatic force acting on particle a? the distance between a and c is 20 meters. particles b and c are fixed in place.

formula for the electrostatic force:
 f = k \times \frac{q1 \times q2}{r {}^{2} }
the answer is 28 micronewtons, but i don't understand how they got that solution?
