The motion of a charged particle P, observed in an inertial frame S. It is found that P moves with constant velocity v through a region of space where there is a uniform electric field E and a uniform magnetic field B. The speed v = |v|and the field magnitudes E = |E| and B = |B| are all non-vanishing.
Use the Lorentz force law to express E in terms of v and B.

The Attempt at a Solution
F/q = E+ v*B
F/q - (V*B) = E
