AB is a vertical tower. The point A is on the ground and C is the middle point of AB. The part CB subtend an angle \[\alpha \]at a point P on the ground. If \[AP=n\,AB,\]then the correct relation is [MNR 1989; IIT 1980]

\[n=({{n}^{2}}+1)\tan \alpha \]

\[n=(2{{n}^{2}}-1)\tan \alpha \]

\[{{n}^{2}}=(2{{n}^{2}}+1)\tan \alpha \]

\[n=(2{{n}^{2}}+1)\tan \alpha \]
