Select the correct statements about Lorentz Force.
I. In presence of electric field \( \vec{E}(r) \) and magnetic field \( \vec{B}(r) \) the force on a moving electric charge is \( \vec{F}=q[\vec{E}(r)+v \times \vec{B}(r)] \)
II. The force, due to magnetic field on a negative charge is opposite to that on a positive charge.
III. The force due to magnetic field are become zero if velocity and magnetic field are parallel or antiparallel.
IV. For a static charge the magnetic force is maximum.
(a) I and II only
(b) II and III only
(c) I, II and III
(d) I, II, III and IV
