Homework Statement
This is not a homework problem so there is no problem statement. More of a conceptual question.
Consider a charge on a ring:
If this was a semicircle opposed to a ring, how would this change the equation since there is not an opposing dEr force.
[tex]
\boldsymbol{E} = \boldsymbol{\hat{z}} \frac{\rho_l R(-\hat{\boldsymbol{r}}R + \hat{\boldsymbol{z}Z})}{4 \pi \varepsilon_0 (R^2 + Z^2)^{3/2}}\int_{0}^{\pi }d\phi
