Two charges -2.34 pC and 7.71 pc are brought together so that the separation between them is r. The magnitude of the force that they exert on each other is 1.75 N. What is the separation between the charges? Provide your answer in millimeters with a precision of two decimal places. Two charges, QA = -2.11 nC and Q3 = 5.68 nC are placed along x-axis at positions 3334 = O m and and :03 = 3.87 cm, respectively. The charges are held stationary. Where along the x-axis should be a third charge 6 be placed so that it experiences no net force? Enter your answer as the x-coordinate of the position. Provide your answer in centimeters with the precision of two places after the decimal
