An electron (q = - 1.6 x 10-19 C, m = 9.11 x 10-31 kg) is travelling directly toward a fixed negative charge (Q = -2.2 x 10-10 C). When it is very far away (r = infinity) the electron has a speed of 5.4 x 105 m/s. How close to the fixed charge will the electron reach before turning around? (Hint: think about energy)
