## Homework Statement

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.

## Homework Equations

Lorentz force formula-

F=q(E+v*B)

## The Attempt at a Solution

F=q(E+v*B)

F/q = E+ v*B

F/q - (V*B) = E
