what is the difference between these two forces ?
F=qE and F=q(V*B)
The former is the expression for the electric force acting on an object of charge q placed in an electric field of field strength E, while the latter is the expression for the magnetic force acting on an object possessing charge q moving with velocity v in the region of a magnetic field with field strength B.
The first is just a vector relation for a charge in an electric field. The second is the Lorentz force on a moving charged particle in a magnetic field. The latter equation is a vector cross product, meaning that F is perpendicular to both the velocity vector and the magnetic field vector.
thanks alot..tomorrow is my exam and i wanted to study about these forces and their differences :)
