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
- Au ^2 ~g
- Bu ^2 ^2 g
- Cu ^2 ^2 g
- 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
