Can you help me with part B ### Educational Exercise on Electric Fields#### Problem DescriptionCharge \(Q\) is uniformly distributed along a thin, flexible rod of length \(L\). The rod is then bent into the semicircle shown in the figure.#### Part AFind an expression for the electric field \(\vec{E}\) at the center of the semicircle.**Hint:** A small piece of arc length \(\Delta s\) spans a small angle \(\Delta \theta = \Delta s/R\), where \(R\) is the radius.Express your answer in terms of the variables \(Q\), \(L\), unit vectors \(\hat{i}\), \(\hat{j}\), and appropriate constants.\[ \vec{E} = \frac{Q}{2\epsilon_0 L^2} \hat{i} \]- **Feedback:** Correct#### Part BEvaluate the field strength if \(L = 12 \, \text{cm}\) and \(Q = 28 \, \text{nC}\).Express your answer with the appropriate units.\[E = \text{Value} \quad \text{Units}\]#### Figure DescriptionThe figure displays a semicircle with charge \(Q\) distributed uniformly along its length \(L\). The semicircle is centered at the origin of a Cartesian coordinate system, with the x-axis extending through the diameter of the semicircle. ### Key Concepts- Understand charge distribution along a curved path.- Apply the concept of electric fields resulting from continuous charge distributions.- Use calculus to integrate the electric field contributions from each segment of the charged semicircle.This exercise tests comprehension in setting up integrals for electric fields in non-linear distributions and calculating resultant vectors from symmetrical charge configurations.
