A charge of 3.97 C is held fixed at the origin. A second charge of 3.50 C is released from rest at the position (1.25 m, 0.570 m). Part A If the mass of the second charge is 2.82 g, what is its speed when it moves infinitely far from the origin? v = Submit Request Answer Part B At what distance from the origin does the second charge attain half the speed it will have at infinity? r ? ? m m/s A charge of 3.97 C is held fixed at the origin.
