Homework Statement
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
Homework Equations
F = Ke*|q1||q2|/(r)^2
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 please? Diagram below for reference.
