Vedclass · Answer

(B) Cathode rays consist of electrons,which are negatively charged particles.When placed in a transverse electric field,these particles experience an electrostatic force $F = qE$.Since the charge $q$ is negative,the force acts in the direction opposite to the electric field vector.Electric field lines point from higher potential to lower potential.Therefore,the force on the electrons acts from lower potential to higher potential,causing them to move up the potential gradient.
