Question

An electron projected with velocity vecv=v0 hati in the electric field vecE=E0 hatj. Trace the path followed by the electron E0 . (A) Parabola (B) Circle (C) Straight line in + y direction (D) Straight line in - y direction

Since, vecv=v0 hati vecE=E0 hati The electron is moving in x-direction perpendicular to the electric field which is in y-direction. Thus, the path of electron moving perpendicular to field will be a parabola.

Q. An electron projected with velocity $v = v_{0} \hat{i}$ in the electric field $E = E_{0} \hat{j}$ . Trace the path followed by the electron $E_{0}$ .

Parabola

Circle

Straight line in + y direction

Straight line in - y direction

Since, $v = v_{0} \hat{i}$
$E = E_{0} \hat{i}$
The electron is moving in x-direction perpendicular to the electric field which is in y-direction.
Thus, the path of electron moving perpendicular to field will be a parabola.
