Homework Equations
L=pi*r/2
λ=q/L
Enet=∑λ(2sinθ)*k
The Attempt at a Solution
So first to calculate L for each arc
L1=pi(.107m)/2
L2=pi(.214m)/2
L3=pi(.321m)/2
and lambda:
λ1=3.3E-6/L1=2E-5
λ2=-12E-6/L2=-3.9E-5
λ3=29.7E-6/L3=5.9E-5
So using θ=pi/2 and rearranging the equation found above with the distributive property i come up with:
k(2sin(π/2)*(2E-5-3.9E-5+5.9E-5)
=508551 N/C
This was incorrect and I am unsure of my mistake(s)
