It is possible to project a particle with a given velocity in two possible ways so as to make them pass through a point p at a horizontal distance r from the point of projection. If t₁ and t₂ are times taken to reach this point in two possible ways, then the product t₁ t₂ is proportional to
Options
- A1 r
- Br
- Cr^2
- D1 r^2
Correct answer
B. r
Step-by-step solution
aligned & T₁= 2 u g & and T₂= 2 u g & T₁ T₂= 2 u^2 g = 2 r g & [ R= v^2 2 g ] & aligned
