Question 2 please Thank you ROT6:47MOA thin plastic rod is bent into the shape of a semicircle of radius a. It is charged negativelywith -Q Coulombs of charge. Show how to derive the equation for the electric field at the originof the coordinate axes in the following diagram.Ө160|||dq1. Identify the position vector for a small portion of the source charge distribution and express itin plane polar coordinates using a unit vector in those coordinates.2. Identify the position vector for the field point and express your answer as 7 = . Recall, the field point is at the origin.
