Find the magnitude of the electrostatic force between a Na + ion and a cl - ion separated by 0.79 nm. N would the answer change if the sodium ion were replaced by li + and the chloride ion by Br -? yes No Explain. This answer has not been graded yet. Three point charges lie along a straight line as shown in the figure below, where q1 = 6.42 muC, q2 = 1.51 muC, and q3 = -2.02 muC. The separation distances are d1 = 3.00 cm and d2 = 2.00 cm. Calculate the magnitude and direction of the net electric force on each of the charges. q1 magnitude N direction q2 magnitude N direction q3 magnitude N direction

2) a) 50.17 N

     b)28.26N

     c) -50.17N
