    A TV tower has a height of 20 m. The maximum distance upto which TV transmission can be received is equal to \[\left( radius of earth = 6.4 \times  1{{0}^{6}}m \right)\]

    A)  \[4 \times  1{{0}^{3}}m\,\]                 

    B)  \[16 \times  1{{0}^{3}}m\,\]

    C)  \[32 \times  1{{0}^{6}}m\,\]                

    D)  \[64 \times  1{{0}^{6}}m\,\]

    Correct Answer: B

    Solution :

      As,        \[{{d}_{\max }}=\sqrt{2hR}\] \[=\,\,\,\sqrt{2\times 6.4\times {{10}^{6}}\times 20}\] \[=\,\,\,\,\,16\times {{10}^{3}}\,m\]
