Question
What are conditions for the projectile path to be annular?

Answer

(i) The angle of projectile should be between 0° to 90° from the horizontal.
(ii) The value of g remains the same at its maximum height.
 (iii) The projectile velocity should not be very hight so that value of air friction remains negligible.
