Homework Statement
Consider a particle of mass m that carries a charge q. Suppose that the particle is under the influence of both an electric field E and a magnetic field B so that the particle's trajectory is described by the path x(t) for a[tex]\leq[/tex]t[tex]\leq[/tex]b. Then the total force acting on the particle is given in mks units by the Lorentz force,
F=q(E + vxB),
where v denotes the velocity of the trajectory.
a) Use Newton's second law of motion (F=ma) to show that
ma.v = qE.v (dot products)
Homework Equations
The Attempt at a Solution
Tried distributing to help make sense of the problem, but didn't do much for me:
ma = qE + q(vxB)
