I figured I would just find the electric field produced at point * by each individual charge and then add them. For example if I were to set E1 to be the top molecule...
*URGENT*Damped Harmonic Motion (Differential Equations)
A damped harmonic oscillator satisfies the following equation: d2x/dt2 = − 5x − 2dx/dt
(a) By assuming a trial function of the form x = A e^qt, determine the solution of this
equation "from scratch." Express your final answer as a real...
I'm sorry but I'm really not following. I guess I could find mass by using m=(density)(volume) but I'm still uncertain on how to express the volume of this object.

You can double check my work but I'm pretty sure I got the first to integrations fine (with respect to s and p)...
Okay, I think I know what you mean.
E=∫kdq/r^2 let dq=λdl and r =(a+x), the distance from the end of the rod to a +x value
E=λk/(a+x)^2∫dl -integrating from -a-L to -a
E=λk/(a+x)^2[(-a)-(-a-L)]
E=λkL/(a+x)^2
How's that look?
edit: I decided to use k rather than 1...
