# By What Percentage Will the Transmission Ranges of Tv Tower Be Affected When the Height of the Tower is Increased by 21%? - Physics

By what percentage will the transmission ranges of TV tower be affected when the height of the tower is increased by 21%?

#### Solution

d_T = sqrt(2Rh_T)

Let the transmission of the tower before transmission be =  vecd_(T_1)

Range after increase in height =d_(T_2)

Ratio = (d_(T_1))/d_(T_2) = sqrt((2Rh_(T_2))/(2Rh_(T_1))) = sqrt(h_(T_2)/h_(T_1))

Height increase = 21%

Thus,121/100 h_(T_1 =  h_(T_2)

(d_(T_2))/(d_(T_1)) = sqrt((121h_(T_1))/(100 h_(T_1)) = 1.1

d_(T_2) :d_(T_1)  11:10
