The mean orbital radius of the earth around the sun is `1.5xx10^(8)` km. Calculate mass of the sun if `G=6.67xx10^(-11)Nm^2"/"kg^(-2)`?

Explanation

To calculate the mass of the sun using the given mean orbital radius of the Earth and the gravitational constant, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Mean orbital radius of the Earth around the Sun, \( r = 1.5 \times 10^8 \) km = \( 1.5 \times 10^{11} \) m (since 1 km = 1000 m).
- Gravitational constant, \( G = 6.67 \times 10^{-11} \, \text{Nm}^2/\text{kg}^2 \).
- Time period of Earth's revolution around the Sun, \( T = 1 \) year = \( 365 \times 24 \times 3600 \) seconds.
