Explanation:
When a particle of mass m and charge q is thrown in a region where uniform gravitational field and electric field are present, its path can be determined by considering the forces acting on it.
Forces acting on the particle:
Possible paths of the particle:
Therefore, the correct answer is options A and C - the path of the particle may be a straight line or a parabola.
When a particle of mass m and charge q is thrown in a region where uniform gravitational field and electric field are present, its path can be determined by considering the forces acting on it.
Forces acting on the particle:
- Gravitational force (Fg) = mg, where g is the acceleration due to gravity
- Electric force (Fe) = qE, where E is the electric field strength
Possible paths of the particle:
- Straight line: If the electric and gravitational forces are in the same direction, the particle will move in a straight line with constant acceleration. The path will be a straight line.
- Parabola: If the electric and gravitational forces are perpendicular to each other, the particle will move in a parabolic path. This happens when the particle is thrown at an angle to the electric field. The path will be a parabola.
- Circle: If the electric force is perpendicular to the gravitational force, the particle will move in a circular path. This happens when the particle is thrown in a direction perpendicular to the electric field. The path will be a circle.
Therefore, the correct answer is options A and C - the path of the particle may be a straight line or a parabola.

A particle of mass m and charge q is thrown in a region where uniform ...
The acceleration due to gravity is insignificant compared with the acceleration caused by the electric field, so the gravitational field can be ignored. Hence, when a particle of mass m and charge q is thrown in a region where uniform gravitational field and electric field are present, before entering the electric field, the charge follows a straight line path (since, no net force due to any of the field). As soon as it enters the field, the charge begins to follow a parabolic path (since, constant force is always in the same direction). As soon as it leaves the field, the charge follows a straight line path (since, no net force due to any of the field). The path of a particle may be straight line or may be parabola.
