A geostationary satellite is orbiting the earth at a height of 6R above the surface of the earth, where R is the radius of the earth. The time period of another satellite at a height of 2.5 R from the surface of the earth is …… hours.

Explanation

To find the time period of a satellite at a height of 2.5R from the surface of the Earth, we can use the relationship between the time period of a satellite and the radius of its orbit. Here’s a step-by-step solution:

### Step 1: Understand the given data
- The height of the geostationary satellite above the Earth's surface is \(6R\).
- The height of the second satellite above the Earth's surface is \(2.5R\).
- The radius of the Earth is \(R\).

### Step 2: Calculate the radius of the orbits
