A body of mass 10 kg lies on a rough horizontal surface. When a horizontal force of F newtons acts on it, it gets an acceleration of 5 m//s^(2) . And when the horizontal force is doubled, it gets an acceleration of 18 m//s^(2) . The coefficient of friction between the body and the horizontal surface is
