Most Important Selected Qs for JEE AdvancedPhysicsMotion in One Dimension
A particle of mass m is projected from O with velocity v ₀ i + v ₀ j . At the same instant, another particle of mass 2 m is projected from point P with v₀ k . The velocity of 2^ nd particle w.r.t first particle after time t= v₀ g is
Options
- Av₀ k +g t j +v₀ i
- Bv₀ k -g t j +v₀ i
- Cv₀ k -v₀ i
- DNone of the above
Correct answer
D. None of the above
Step-by-step solution
At t= v₀ g , v₁ =v₀ i aligned & v ₂ = v ₀ k - gt j & v ₂ - v ₁ = v ₀ k - gt j - v ₀ i aligned
