Which one of the following is not correct about Lorentz Force?

Options

A. In presence of electric field `vecE(r)` ang magnetic field `vecB(r)` the force on a moving electric charge is `vecF=q[vecE(r)+vecvxx vecB(r)]`
B. The force, due to magnetic field on a negative charge is opposite to that on a positive charge.
C. The force due to magnetic field becomes zero if velocity and magnetic field are parallel or anti- parallel.
D. For a static charge the magnetic force is maximum.

Answer

D

Explanation

If charge is not moving then the magnetic force is zero.
Since `vecF_(m)=q(vecv xxvecB)`
As, `vecv=0`, for stationary charge`" "therefore vecF_(m)=0`
