Mass m1 moves on a slope making an angle  with the horizontal and is attached to mass m2 by a string passing over a frictionless pulleys as shown. The coefficient of friction between m1 and the sloping surface is . The correct statement among the following is 1) If m m sin 2 1   , the body m1 will move up the plane 2) If   m m sin cos 2 1      , the body m1 will move up the plane 3) If   m m sin cos 2 1      , the body m1 will move up the plane 4) If   m m sin cos 2 1      , the body m1 will move up the plane
