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).

Text Solution

Verified by Experts

The trajectory of a particle under gravitational force of the earth will be a conic section (for motion outside the earth) with the centre of the earth as a focus. Only (c) meets this requirement
Note. The trajectory of the particle depends upon the velocity of projection. Depending upon the magnitude and direction of velocity it may be parabolic or elliptical

Statement I: A disc is allowed to roll purely on an inclined plane as shown in Fig. A force F parallel to the incline and passing through the centre of the disc acts which remains constant during the motion.
