. The center of the moon is 0.0026 AU (3.890 x 108m) from the center of the Earth and has a relativemass of 0.0123.(a) (2 points).Locate the cm of the Earth-Moon system with respect to the center of the Earth. With respect to the center of the center of the Moon.(b) (2 points).Find the ratio of orbital velocities of the Earth and Moon about the cm of thesystem. If the orbital velocity of the Moon is 1012 m/s, what is the approximate orbital velocity of theEarth about the cm of the Earth-Moon system

grav potential energy

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
