Question

A particle of mass 'm' and charge q moves at a high speed along the X axis. Initially it is near -infinity and then in a short time moves to positive infinity. Another charge Q is fixed at (0,-d) . As the moving charge passes the stationary charge, the X component of its velocity does not change appreciably but it acquires a small velocity in the y direction. Determine the angle through which the moving charge is deflected.
