A positively charged particle is placed at the origin (with zero initial velocity) in the presence of a constant electric and a constant magnetic field along the positive z and x directions, respectively. At large times, the overall motion of the particle is adrift along the

Concept:

The curve generated by a point on the circumference of a circle that rolls along a straight line is known as Cycloid.

Calculation:

Initially charged particle will experience electric force and will gain velocity then it will deflect in magnetic field

F ∝ (v×B) → y

The correct answer is option (1).
