getting mass into the equation was easy enough - use the field E to get a force F. then simply take F=ma and rearrange

OK, so I'm assuming that I am using r^2=x^2+d^2, and that x=r tan \theta, which should give me the distance, as I can't see another way of getting it. but this complicates things on the rhs giving me a "+1 " when simplified, which looks tough to get rid of. I still can't see a way of getting...

Homework Statement A Particle of mass m and chargeq oves at high speed along the x axis. It is 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 chrge, its x component o velocity does not...
