Question 1 1 pts A wire with uniform linear charge density A = +1.50 x 10 C/m extends along the x-axis from -o to a = -1.00 m, as shown in the figure below. Which one of the following expression gives the infinitesimal electric field at the origin, dE, generated by the small segment of wire da at a distance x from origin? [Select ] A. k Adz 2 +a 2 B. KAda a2 C. K Ada D. K Adri a-I E. K Ada Ita Integration over the entire wire gives the total electric field at the origin. Which one of the following is the correct electric field magnitude? [Select ] A. 2.70 x 104 N/C B. 1.35 x 104 N/C C. 3.88 x 104 N/C D. 1.20 x 103 N/C E. 2.45 x 103 N/C dE x x+ dx a 0 X
