Step-by-step solution

Given: A charged particle is introduced at the origin ((x=0, y=0, z=0) ). initial velocity (= v ), uniform electric field ( E ). uniform magnetic field ( B ). Also the values are given the table. we need to find the cases where the particle will move in a straight line with constant velocity. To move a particle with constant velocity; Fnet (=0 ), ( ) The electric force (= ) magnetic fore e. ( gathered q E=q v B . E=v B . gathered ) Now checking the options.
