If the water falls from a dam into a turbine wheel (19.6 ~m ) below, then the velocity of water at the turbines, is (Take (g=9.8 ~m / s ^2 ) )

Options

  1. A(9.8 ~m / s )
  2. B(19.6 ~m / s )
  3. C(39.2 ~m / s )
  4. D(98.0 ~m / s )

Correct answer

B. (19.6 ~m / s )

Step-by-step solution

(v= 2 g h = 2 9.8 19.6 =19.6 ~m / s ).
