A T.V. tower has a height of 100m. How much population is covered by the T.V. broadcast if the average population density around the tower is `1000 per sq.km.Radius of the earth `6.37xx10^(6)m`.By how much height of the tower be increased to double to its coverage range?

Explanation

To solve the problem step-by-step, we will first calculate the coverage area of the TV tower and then determine how much we need to increase the height of the tower to double that coverage.

### Step 1: Understand the given data
- Height of the tower (H1) = 100 m
- Average population density (ρ) = 1000 people/km² = \(1000 \times 10^{-6}\) people/m²
- Radius of the Earth (R) = \(6.37 \times 10^6\) m

### Step 2: Calculate the coverage distance (D)
