Question
Two charges are located on the x axis: q1 = +4.6C at x1 = +5.7 cm, and q2 = +4.6C at x2 = -5.7 cm. Two other charges are located on the y axis: q3 = +2.9C at y3 = +4.3 cm, and q4 = -11C at y4 = +7.6 cm. Find (a) the magnitude and (b) the direction of the net electric field at the origin.
Two charges are located on the x axis: q1 = +4.6C at x1 = +5.7 cm, and q2 = +4.6C at x2 = -5.7 cm. Two other charges are located on the y axis: q3 = +2.9C at y3 = +4.3 cm, and q4 = -11C at y4 = +7.6 cm. Find (a) the magnitude and (b) the direction of the net electric field at the origin.Explanation / Answer
q1 = +7.5C at x1 = +4.1 cm q2 = +7.5C at x2 = -4.1 cm. q3 = +3.6C at y3 = +5.0 cm q4 = -8.1C at y4 = +6.3 cm as q1 = q2 and origin is their mid point. so the net electricfield due to q1 and q2 =0 the net elctric field at origin = E3 +E4 = (1/4*pi*e)[8.1/6.3^2 - 3.6/5^2] * 10^6 = 8.987 x 109 * 0.06 * 10^6 = 5.3*10^14 N/c direction is along positive y-axis
