A particle of mass m and charge q moves at high speed along x axis. It it initially near x=-infinity and it ends up near x=+infinity. A second charge Q is fixed at the point x=0, y=-d. As the moving charge passes the stationary charge, its x component of 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.

im quite poor in integration.. any hints, anyone?

We need to see some of your work before we can help you -- PF rules. What is the vector force on the moving charge due to the fixed charge, as a function of position? Show us how you set up the integral that you are having trouble with.
