(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Calculate the magnitude and direction of the Coulomb force on each of the three charges shown in the figure below.

a) 6.00 microcoloumbs

b)1.50 microcouloumbs

c)-2.00 microcouloumbs

2. Relevant equations

F = Ke*|q1||q2|/(r)^2

3. The attempt at a solution

a) 6*10^-6 * (1.50^-6)/(.03)^2 * 8.99^10^(-9) = 90, with direction to the right.

b) 1.50*10^(-6) * -2.00*10^(-6) * 8.99 * 10^(9) = -67.425 + 90 = 22.58, with direction towards the right.

c) The answer is just -67.425, towards the left.

Is this correctly done? If not, can anyone explain what I did wrong and tell me correct method plz? Diagram below for reference.
