Questions
From an inclined plane two particles are projected with same speed at same angle θ, one up and the other down the plane as shown in fig. (3). Which statement(s) is/are correct?
detailed solution
Correct option is B
The projection of projectiles P and Q are separately shown in fig, (a and b) respectively.The time of flight of P is given byTp=2usin(α−β)gcosβ=2usin(2θ−θ)gcosθ=2utanθgThe time of flight of Q is given byTQ=2usin(α+β)gcosβ=2usinθgcosθ=2utanθg∴ TP=TQTalk to our academic expert!
