Charge q1q1 = +6.00 nCnC is at xx = 0, yy = 0.200 mm and charge q2q2 = -6.00 nCnC is at xx = 0, yy = -0.200 mm. Find the magnitude of the total electric force exerted by q1q1 and q2q2 on a third charge q3q3 = -2.50 nCnC at xx = 0.150 mm, yy = 0. Find the direction of the total electric force exerted by q1q1 and q2q2 on q3q3 as an angle measured from the +x+x-axis toward the +y+y-axis.
