In 1897, J.J. Thomson "discovered" the electron by measuring the charge-to-mass ratio of "cathode rays" (actually,streams of electrons, with charge q and mass m) as follows:

\ \ (a)First he passed the beam through uniform crossed electric and magnetic field $vecE$ and $vecB$ mutually perpendicular, and both of them perpendicular to the beam), and adjusted the electric field until he got zero deflection. What, then, was the speed of the particles (in terms of E and B)? \ \

(b) Then he turned off the electric field, and measured the radius of curvature, R, of the beam, as deflected by the magnetic field alone. In terms of E, B, and R, what is the charge-to-mass ratio (q/m) of the particles?

ok this is my code. I get the error that there is no line to end. and then i do not get an empty line between the intro and a, and between a and b.
