Question

Two practicles are projected simultaneously from the same point on ground at angle ${73}^o$ and ${53}^o$ with horizontal with speed $V$ and $2V$ in the same vertical plane, then relative velocity between them when both are in air (neglect the air resistance).

• A. Is always vertical
• B. Becomes zero once
• C. Is changing continuously
• D. Is constant

Answer 1

Answer: (D)

Is constant

Relative velocity between both of them will be constant as both of them are experiencing identical gravity force so no relative change in velocities will occur.
