Shown are several cuves (fig. (a), (b), (c), (d), (e), (f)]. Explain with reason, which ones amongst them can be possible trajectories traced by a projectile (neglect air friction).

Explanation

The nature of trajectory of a particle under the action of gravitational force of earth will be a parabolic rather a conic section for motion outside the earth with focus lting at the centre of the earth. Only option (c ) meets this requirement.
