A particle having a mass of `10^(-2)` kg carries a charge of `5 xx 10^(-8)` C. The particle is given an initial horizontal velocity of `10^(5) ms^(-1)` in the presence of electric field `vecE` and magnetic field `vecB`. To keep the particle moving in a horizontal direction, it is necessary that.
(1) `vecB` should be perpendicular to the direction of velocity and `vecE` should be along the direction of velocity.
(2) Both `vecB` and `vecE` should be along the direction of velocity.
(3) Both `vec B and vec E` are mutually perpendicular and perpendicular to the direction of velocity.
(4) `vec B` should be along the direction of velocity and `vecE` should be perpendicular to the direction of velocity Which one of the following pairs of statements is possible?
