A particle of mass 73 g and charge 38muC is released from rest when it is 46 cm from a second particle of charge -17muC. Determine the magnitude of the initial ac- celeration of the 73 g particle. Answer in units of m/s^2. Well, I used this formula: k [(q1 * q2) / mr^2)] 8.98755*E9 [(38*17)/ ((73/1000)*(.46^2))] edit - fixed typo = 3.7586 * E14 But it's wrong... any help appreciated. Thanks.
