A large number of bullets are fired in all directions with same speed ' U '. The maximum area on the ground on which the bullets will spread is

Options

  1. Au ^2 ~g
  2. Bu ^4 ~g ^2
  3. C^2 u^4 g^2
  4. D^2 u^2 g^2

Correct answer

B. u ^4 ~g ^2

Step-by-step solution

Area in which bullet will spread = r^2 For maximum area, r=R_ = u ^2 ~g [ . when . =45^ ] Maximum area R _ ^2= ( u ^2 ~g )^2= u ^4 ~g ^2
