Two balls with same mass and initial velocity, are projected at different angles in such a way that maximum height reached by first ball is 8 times higher than that of the second ball. T₁ and T₂ are the total flying times of first and second ball, respectively, then the ratio of T₁ and T₂ is :

Options

  1. A2 2 : 1
  2. B2: 1
  3. C2 : 1
  4. D4: 1

Correct answer

A. 2 2 : 1

Step-by-step solution

aligned & Given, ( H _ )₁=8 ( H _ )₂ & u ^2 ^2 ₁ 2 ~g =8 u ^2 ^2 ₂ 2 ~g & ₁=2 2 ₂ & ~T ₁ ~T ₂ = 2 u ₁ / g 2 u ₂ / g = ₁ ₂ =2 2 aligned
