A vertical air stream flowing at a velocity of 100 m/s supports a ball of 60 mm in diameter. Taking the density of air as 1.2 kg/m$$^3$$ and kinematic viscosity as 1.6 stokes, the weight of the ball that is supported is (if coefficient of drag $$C_D = 0.8$$)

A

20.2 N

B

13.5 N

C

30.1 N

D

25.2 N
