Can someone please solve this problem?

(14%) Problem 5: A 3-D printer lays down a semicircular arc of positively charged plastic with a radius R = 3.4 cm, and a linear charge density of 1 = +1.6 uC/m. After the printer has finished the are, the de stylus moves to the center of the are as shown. The minute segment of the plastic are highlighted in the diagram subtends an angle do. Stylus tip R X theexpertta.com 14% Part (a) Input an expression for the charge dq on the segment of size do in terms of given parameters. dq = AR de Correct! 4 14% Part (b) Input an expression for the electric field vector, dE, generated at the center of the arc by the minute segment of plastic subtending the arc de. Express your answer in terms of given parameters, the Coulomb constant k, and the unit vectors i and j. 14% Part (c) Evaluate the expression from part (b) as an indefinite integral to determine the x-component of the electrical field, Ex, at the center of the arc generated by the entire line of charged plastic.
