Vedclass · Answer

(B) The range $d_T$ of a transmitting antenna of height $h_T$ is given by the formula: $d_T = \sqrt{2Rh_T}$.Here, $d_T = 12.8 \ km = 12.8 	imes 10^3 \ m$ and $R = 6400 \ km = 6400 	imes 10^3 \ m$.Rearranging the formula to solve for $h_T$:$h_T = \frac{d_T^2}{2R}$.Substituting the values:$h_T = \frac{(12.8 	imes 10^3)^2}{2 	imes 6400 	imes 10^3}$.$h_T = \frac{12.8 	imes 12.8 	imes 10^6}{12800 	imes 10^3}$.$h_T = \frac{163.84 	imes 10^6}{12.8 	imes 10^6}$.$h_T = 12.8 \ m$.

$A$ transmitting antenna covers a range of $12.8 \ km$. Find the height of the antenna in $m$. (Radius of the Earth $= 6400 \ km$)
