The top of a smooth inclined plane of length 20√2 m is connected to the edge of a well of diameter 40° 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)
