It is 7850 m/s

Explanation:

The orbital velocity is given by

$v = \sqrt{\frac{GM}{r}}$

where, G be the universal gravitational constant, M be the mass of earth and r be the distance of moon from earth.

$G = 6.67\times 10^{-11} Nm^{2}/kg^{2}, M = 5.98\times 10^{24}kg, r = 6.47\times 10^{6}m$

$v = \sqrt{\frac{6.67\times 10^{-11}\times 5.98\times 10^{24}}{6.47\times 10^{6}}}$

v = 7850 m/s
