The force required to just move a body up the inclined plane is double the force required to just prevent the body from sliding down the plane. The coefficient of friction is\[\mu \]. The inclination \[\theta \] of the plane is

• A. \[{{\tan }^{-1}}\mu \]
• B. \[{{\tan }^{-1}}\left( \mu /2 \right)\]
• C. \[{{\tan }^{-1}}2\mu \]
• D. \[{{\tan }^{-1}}3\mu \]
