BPSC – Combined Competitive Examination · ಪ್ರಶ್ನೆ 21
Two objects of different masses falling freely near the surface of the Moon would:
ಉತ್ತರ ತೋರಿಸು ಮತ್ತು ವಿವರಣೆ
ಉತ್ತರ: (C) have the same velocity at any instant
ವಿವರಣೆ
On the airless Moon all bodies fall with the same acceleration (~1.62 m/s²), so released together they have equal velocities.
- (A) ತಪ್ಪು
Wrong: free-fall acceleration is independent of mass.
- (B) ತಪ್ಪು
Wrong: inertia depends on mass, which does not change.
- (C) ಸರಿ
Correct: with no air and equal acceleration, their velocities stay equal.
- (D) ತಪ್ಪು
Wrong: force (weight) is proportional to mass, so differs.
