Question

Statement I:A projectile that traverses a parabolic path show deviation from its idealised trajectory in the presence of air resistance.
Statement II:Air resistance affect the motion of the projectile.

• A. If both statement I and statement II are true and statement II is the correct explanation of statement I.
• B. If both statement I and statement II are true but statement II is not the correct explanation of statement I.
• C. If statement I is true but statement II is false.
• D. If both statement I and statement II are false.

Answer 1

Answer: (A)

In the presence of dissipative forces like air friction which opposes the motion, any object will lose some part of its initial energy and consequently momentum too. Thus a projectile that traverses a parabolic path would certainly show deviation from its idealized trajectory in the presence o f air resistance.
