Assertion:

In an electric field, an electron beam perpendicular to the field is deflected along a parabola, and in a magnetic field, the electron path perpendicular to the field will be circular
Reason:

In an electric field, force is perpendicular to the path and along the field. In a magnetic field, force is perpendicular to both the magnetic field and the path of the beam
Explanation:
Electric fields apply a force on charged particles along the direction of the field. When an electron beam is perpendicular to the electric field, the force acts perpendicular to the path, resulting in a parabolic trajectory. This is because the electron experiences a constant force due to the electric field.
On the other hand, in a magnetic field, the force experienced by a charged particle is perpendicular to both the magnetic field and the direction of the particle's motion. When the electron path is perpendicular to the magnetic field, the force acts in a direction that causes the electron to move in a circular path. This is known as the Lorentz force and is responsible for the circular motion of charged particles in a magnetic field.
Therefore, the assertion is correct because the electron beam is deflected along a parabola in an electric field and moves in a circular path in a magnetic field when perpendicular to the field. The reason is also correct as it explains the underlying principles of the forces acting on the electron in each field, supporting the assertion. Hence, option A is the correct choice.
