The top of a smooth inclined plane of length 20 2 ~m is connected to the edge of a well of diameter 40 ~m making an angle 45^ as shown in figure. A body is projected along the inclined plane with a velocity ' u '. If the body crosses the well without falling in it then the minimum value of ' u ' is ( g =10 ~ms ⁻² )
Options
- A20 ~ms ⁻¹
- B20 2 ~ms ⁻¹
- C10 2 ~ms ⁻¹
- D15 2 ~ms ⁻¹
