Two particles X and Y, of equal mass and with unequal positive charges, are free to move and are initially far away from each other. With Y at rest, X begins to move towards it with initial velocity u. After a long time, finally (a) X will stop, Y will move with velocity u (b) X and Y will both move with velocities u/2 each (c) X will stop, Y will move with velocity < u (d) both will move with velocities < u/2 |

Answer» Correct Answer is: (a) X will stop, Y will move with velocity u This is similar to one-dimensional, elastic collisions between bodies of equal masses, and results in exchange of velocities. |
