A projectile can have the same range R for two angles of projection. If T₁ and T₂ be the time of flights in the two cases, then the product of the two time of flights is directly proportional to

Options

  1. A1 / R^2
  2. B1 / R
  3. CR
  4. DR ^2

Correct answer

C. R

Step-by-step solution

Range is same for complimentary angles. T ₁= 2 u g and T ₂= 2 u (90- ) g and R= u^2 2 g T ₁ ~T ₂= 2 u g 2 u g = 2 R g .
