Two equal charges, each of chargeQ= -19.00 C and massm= 5.0 mg, are held 46.0 cm apart. a) If they are released from rest at the same instant, how fast will they be moving when they are very far away from each other? 1.1910³m/s

b) Now consider the charges back in their original configuration. How much work would be required to move a chargeq= -0.32 C from the midpoint of the charges to a pointd= 20.70 cm closer to either of the charges?
