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 need to find the population covered by the TV broadcast and the required increase in height of the tower to double its coverage range.

### Step 1: Understand the given data
- Height of the tower (h) = 100 m
- Radius of the Earth (R) = 6.37 × 10^6 m
- Average population density (ρ) = 1000 people/km² = 1000 × 10^(-6) people/m² = 10^(-3) people/m²

### Step 2: Find the coverage radius (d)
