Question

A particle of mass $1\times {10}^{-26}$ $kg$ and charge $1.6\times {10}^{-19}$ $C$ travelling with a velocity $1.28\times {10}^{6}m{s}^{-1}$ along the positive $X-$axis enters a region in which there is a uniform electric field $\overrightarrow{E}=-102.4\times {10}^{3}kN{C}^{-1}$ and magnetic field $\overrightarrow{B}=8\times {10}^{-2}\hat{j}Wb{m}^{-2}$ , the direction of motion of the particles is :

Answer 1

Force acting on the particle when it enters in the electric field & magnetic field is
