#### A particle having a mass of kg carries a charge of . The particle is given an initial horozontal velocity of in the presence of electric field and magnetic field . To keep the particle moving in a horizontal direction, it is necesary that(1) should be prependicular to the  direction of velocity and should be along the direction of velocity.(2) Both and should be along  the direction of velocity.(3) Both and are mutually prependicular and prependicular to the direction of velocity.(4) should be along the direction of velocity and should be prependicular to the direction of velocity.Which one of the following pairs of statements is possible? Option 1) (2) and (4) Option 2) (1) and (3) Option 3) (3) and (4) Option 4) (2) and (3)

Lorentz Force -

- wherein

Lorentz equation

For particle to move along a horizontal direction either net force is zero or force is along direction of valocity. This can happen when
