Two projectiles are fired from ground with same initial speeds from same point at angles (45^ + ) and (45^ - ) with horizontal direction. The ratio of their times of flights is

Options

  1. A1
  2. B1- 1+
  3. C1+ 2 1- 2
  4. D1+ 1-

Correct answer

D. 1+ 1-

Step-by-step solution

₁=45+ ; ₂=45- Time of flight, T = 2 v g T ₁ ~T ₂ = (45+ ) (45- ) T ₁ ~T ₂ = 1 2 + 1 2 1 2 - 1 2 T ₁ ~T ₂ = + - = 1+ 1-
