Question

A particle of mass m and charge q is thrown from a point in space where uniform gravitational field & electric field are present. The particle (1) may follow a straight line (2) may follow a circular path (3) may follow a parabolic path

TestHub · Accepted Answer

When force due to the gravitation field is equal to force due to the electric field, the particle must follow a straight-line path with acceleration.
when force due to gravitation field is not equal to force due to the electric field, the particle will follow the path of a parabola,

Hence $1$ and $3$ both are correct
