Problem

The Moon of mass

7.4\times10^{22}\,\text{kg}

revolves around Earth in a nearly circular orbit of radius

3.84\times10^{8}\,\text{m}

with an orbital speed of

1.02\times10^{3}\,\text{m}\,\text{s}^{-1}

. Determine the magnitude of the centripetal force acting on the Moon and state which fundamental force provides this centripetal force.
