A particle having a mass of  ${10}^{-2}$ kg carries a charge of 5 $\times$ 10^-6C. The particle is given an initial horizontal velocity of $5\times {10}^{-8} \raisebox{1ex}{$m$}\!\left/ \!\raisebox{-1ex}{$s$}\right.$ in the presence of electric field $\overrightarrow{\mathrm{E}}$  and  magnetic field $\overrightarrow{\mathrm{B}}$. To keep the particle moving in a horizontal direction, it is necessary that 

 ( 1 )  B should be perpendicular to the direction of velocity and E should be along the direction of velocity. 

 ( 2 )  Both B and E should be along the direction of velocity.

 ( 3 ) Both B and E are mutually perpendicular and perpendicular to the direction of velocity. 

(4)  E should be perpendicular to the direction of velocity.

Which one of the following pairs of statements is possible?
