some one please tell me what force/charge means, i can't imagine it.
Electric field, E, is force/charge …
that just means that the force on a body with charge q is qE …
so force is proportional to charge, and also proportional and parallel to the electric field
The Lorentz force on a charge q is
F = qE + q(v x B)
where v x B (force/charge) represents the vector cross product of v (velocity) and B (magnetic field).
