Texts: Three point charges are located on a circular arc as shown in the figure below. (Let r = 3.68 cm. Assume that the +x-axis is to the right and the +y-axis is up along the page.) Three point charges lie on a circular arc, where the circle has center point P and radius r. A charge of −2.00 nC is a distance r to the left of P. A charge of +3.00 nC is above and to the left of P by a distance r, rotated up along the arc 30.0° from the −2.00 nC charge. A charge of +3.00 nC is below and to the left of P by a distance r, rotated down along the arc 30.0° from the −2.00 nC charge.
(a) What is the total electric field at P, the center of the arc? magnitude N/C direction ---Select--- to the left to the right upwards downwards
(b) Find the electric force that would be exerted on a −5.35 nC point charge placed at P. magnitude N direction ---Select--- to the left to the right upwards downwards

-2.00 nC charge is a distance r to the left of P.
+3.00 nC charge is above and to the left of P by a distance r, rotated up along the arc 30.0° from the -2.00 nC charge.
+3.00 nC charge is below and to the left of P by a distance r, rotated down along the arc 30.0° from the -2.00 nC charge.
