Answer:
![G=6.67* 10^(-11)\ Nkg^2/m^2=0.0000000000667\ Nkg^2/m^2](https://img.qammunity.org/2020/formulas/physics/middle-school/l09ilxaz7t4ghndj1cpinat97eg4otjaob.png)
Step-by-step explanation:
The attractive force acting between any tow masses is given by :
![F=G(m_1m_2)/(r^2)](https://img.qammunity.org/2020/formulas/physics/college/3dvwt85arc70gpu4if1e01gqo5ilrdyvtu.png)
G is the universal gravitational constant
The value of G is,
![G=6.67* 10^(-11)\ Nkg^2/m^2](https://img.qammunity.org/2020/formulas/physics/middle-school/7isdz153wcz02x6fyb9mol5yd718fwc8zm.png)
We need to write the value of G in standard notation. A number is written in scientific notation as :
![N=a* 10^b](https://img.qammunity.org/2020/formulas/physics/middle-school/hnvkd3m0ewlu13p2kz6asp6ylud1uc5hx0.png)
The given value of G is in scientific notation. Its standard notation is given by :
![G=6.67* 10^(-11)\ Nkg^2/m^2=0.0000000000667\ Nkg^2/m^2](https://img.qammunity.org/2020/formulas/physics/middle-school/l09ilxaz7t4ghndj1cpinat97eg4otjaob.png)
So, the correct option is (d). Hence, this is the required solution.
