Q. A proton moves with a velocity of $5 \times 10^{6} \hat{ j}\, ms ^{-1}$ through the uniform electric field, $\vec{ E }=4 \times 10^{6}[2 \hat{ i }+0.2 \hat{ j }+0.1 \hat{ k }] Vm ^{-1}$ and the uniform magnetic field $\vec{ B }=0.2[\hat{ i }+0.2 \hat{ j }+\hat{ k }] T$. The approximate net force acting on the proton is
