The electric potential:
The charge carried by the piece of wire is given by,
, where λ is the linear charge density.
To calculate the electric potential at the center of the semicircle due to the right wire:
dVright = kdq/x
Integrating both sides from x = R to 3R:
What is the electric potential at the center of the semicircle?
Give your answer in terms of λ, R, ϵ 0 and appropriate constant
