Find the acceleration of a particle placed on the surface of the earth at the equator, due to the earth rotation. The radius of earth is 6400 km and time period of revolution of the earth about its axis is 24 h.

Explanation

To find the acceleration of a particle placed on the surface of the Earth at the equator due to the Earth's rotation, we will follow these steps:

### Step 1: Convert the radius of the Earth into meters
The radius of the Earth is given as 6400 km. We need to convert this into meters.

\[ R_E = 6400 \, \text{km} = 6400 \times 10^3 \, \text{m} = 6.4 \times 10^6 \, \text{m} \]
