Gravitation

Question: The mass of the earth is $6.00 imes {10^{24}}\,kg$ and that of the moon is $7.40 \times {10^{22}}\,kg$. The constant of gravitation $G = 6.67 \times {10^{ - 11}}\,N - {m^2}/k{g^2}$. The potential energy of the system is $ - 7.79 \times {10^{28}}\,joules$. The mean distance between the earth and moon is

1) $3.80 \times {10^8}\,metres$

2) $3.37 \times {10^6}\,metres$

3) $7.60 \times {10^4}\,metres$

4) $1.90 \times {10^2}\,metres$
