Two uniform solid balls of same density ...

Two uniform solid balls of same density and if radii `r` and `2r` are dropped in air and fall vertically downwards. The terminal velocity of the ball with radius `r` is `1cms^-1`, then the terminal velocity of the ball of radius `2r` will be (neglect buoyant force on the balls.)
