Question 1

A:- Range is increasing continuously when we increases angle of projection from 0 to 45° from horizontal.
R:- When a particle is projected at angle 60° to the horizontal then at any instant of flight velocity of particle becomes perpendicular to initial direction of motion.

Answer 1

(2)

R:- agar angle 45° se kam hai may kisi instant par velocity, intial ke 90° par nhi ho skati Lakin angle agr 45° se jyda hai tab ho sakti hai

Question 2

A:- In ground to ground projectile motion path of projectile is not semicircular.
R:- In parabola, radius of curvature changes continuously.

A:- जमीन से जमीन पर प्रक्षेप्य की गति में प्रक्षेप्य का पथ अर्धवृत्ताकार नहीं होता है।
R:- परवलय में वक्रता त्रिज्या निरंतर बदलती रहती है।

Answer 2

(1)

Question 3

A:- The path of a projectile with respect to another projectile is straight line.
R:- The acceleration of one projectile with respect to the other is zero.

Answer 3

Both are correct + Explaination

Question 4

A:- A food packet is dropped from an aeroplane flying horizontally, the path of packet os straight line for the pilot.
R:- Horizontal velocity of plane and food packet is same.

A:- एक भोजन का पैकेट क्षैतिज रूप से उड़ रहे हवाई जहाज से गिराया जाता है, पायलट के लिए पैकेट का मार्ग सीधी रेखा में है।
