A charge of 3.45 micro C is held fixed at the origin. A second charge of 3.45 micro C (micro = x10^-6) is released at the position (1.15m, .77 m). a. If the mass of the second charge is 2.3 g, what is the speed when it moves infinately far from the origin? b. At what distance from the origin does the 3.45 micro C charge attain half the speed it will have at infinity? I tried very hard to use the equations I know but am unaware of the ones that can be useful here.
