## Homework Statement

Determine the magnitude of the force between two point charges, Q1 = -2e located at (-3.60 cm, +4.10 cm) and Q2 = -8e located at (-0.60 cm, -8.60 cm). Give your answer in the form "a.bc x 10^(y) N".

## Homework Equations

F = kq1q2/r2

## The Attempt at a Solution

a.) I changed the unit vectors to meters, then I added, squared, and got the square roots of the vectors to get r = sqrt(((-0.036 +(- 0.006))^2)+((0.041+(-0.08))^2))

b.) Then I multiplied the value of "K" by the value of "8e" and "2e" and divided all three values by r^2
