Homework Statement
An object with charge +2.0×10−5 C is moved from position C to position D in the figure (Figure 1) . q1 = q3 = +10.0×10−5 C and q2 = −20.0×10−5 C. All four charged objects are the system.
Here's a picture to the problem
Homework Equations
$$ F = \frac {kq_1 q_2}{r^2} $$
$$ U_e = \frac {kq_1 q_2}{r} $$
$$ a^2+b^2=c^2 $$
The Attempt at a Solution
I first attempted finding all the energy for the system by finding the initial potential electric energy for each pair of charged objects and added them together. I managed to find the distance from ## q_2 ## to ## q_1## and ##q_3## using Pythagorean theorem.$$ c → q_1, c → q_2, c → q_3, q_2 → q_1, q_2 → q_3 $$
Unfortunately after putting the added energies it came up as wrong.
