Let to the right be the +x direction and up along the screen be the +y direction. +3.00 nC -2.00 nC. +3.00 nC Ca) What is the total electric field at P, the center of the arc? db) Find the electric force that would be exerted on a -4.91-nc point charge placed at P. Need Help? omi Answer Save Progress Practice version Home My Assignments Extension Reques/ aExplanation / Answer
a) Net Horizontal field = 8.98 * 109 * 10-9 * (3 * cos30/0.04322 + 3 * cos30/0.04322 - 2/0.04322)
= 15379.29 N/C
Net Vertical field = 8.98 * 109 * 10-9 * (3 * sin30/0.04322 - 3 * sin30/0.04322 )
= 0 N/C
Thus, total electric field = (15379.29 i + 0 j) N/C
b) electric force = - 4.91 * 10-9 * (15379.29 i + 0 j)
= ( - 7.55 * 10-5 i + 0 j) N
