A stone is projected at angle ' ' with velocity ' u '. If it executes nearly a circular motion at its maximum point for short time, the radius of the circular path will be ( g = acceleration due to gravity)

Options

  1. Au ^2 ~g
  2. Bu ^2 ^2 g
  3. Cu ^2 ^2 g
  4. Du ^2 ^2 2 ~g

Correct answer

B. u ^2 ^2 g

Step-by-step solution

Horizontal velocity at highest point: v _ x = u _ x = u a = v _ x ^2 R a=g R = v _ x ^2 ~g = ( u )^2 ~g = u ^2 ^2 g
