Answer:
It is 7850 m/s
Explanation:
The orbital velocity is given by
[tex]v = \sqrt{\frac{GM}{r}}[/tex]
where, G be the universal gravitational constant, M be the mass of earth and r be the distance of moon from earth.
[tex]G = 6.67\times 10^{-11} Nm^{2}/kg^{2}, M = 5.98\times 10^{24}kg, r = 6.47\times 10^{6}m[/tex]
[tex]v = \sqrt{\frac{6.67\times 10^{-11}\times 5.98\times 10^{24}}{6.47\times 10^{6}}}[/tex]
v = 7850 m/s
