A small back starts slipping down from a point B on an inclined plane AB, which is making an angle `theta` with the remaining section CA is rough with a coefficient of friction `mu`. It is found that bottom (point A) of the inclined plane. If `BC = 2AC,` the coefficient of friction is given by `mu = K "tan" theta`
The value of K is ________.
