Is general relativity really a theory of relativity? The magnetic force (Lorentz force) provides the centripetal force in this case, as Fc = mv 2 / r Since, here sin = 1 Then, the magnetic force: F = qvB Now, if the Lorentz magnetic force provides the centripetal force, therefore, these force must be equal as: qvB = mv 2 / r Solve the above expression for r as, r = mv / qB How can we prove that the supernatural or paranormal doesn't exist? We point the first finger in the direction of the field and the thumb in the direction of the force.
