A water fountain on the ground sprinkles water all around it. If the speed of water coming out of the fountain is v , the total area around the fountain that gets wet is :

Options

  1. Av^4 g^2
  2. B2 v^4 g^2
  3. Cv^2 g^2
  4. Dv^4 g

Correct answer

A. v^4 g^2

Step-by-step solution

Max. range = u^2 ~g i.e., v^2 ~g (radius of circle) Area occupied = ( v ^2 ~g )^2= v ^4 ~g ^2
