Consider the motion of a positive point charge in a region where there are simultaneous uniform electric and magnetic fields 0 ˆ E E j = ur and 0 ˆ B B j. = r At time t = 0, this charge has velocity v r in the x-y plane, making an angle ? with the x-axis. Which of the following option(s) is (are) correct for time t > 0? (A) If 0 , ? = ° the charge moves in a circular path in the x-z plane. (B) If 0 , ? = ° the charge undergoes helical motion with constant pitch along the y-axis. (C) If 10 , ? = ° the charge undergoes helical motion with its pitch increasing with time, along the y-axis. (D) If 90 , ? = ° the charge undergoes linear but accelerated motion along the y-axis.
