Answer 1

At some instant it splits into two equal masses .The first mass move in a circular orbit of radius r/2 and the other mass in circular orbit of radius R about of planet of mass M. At some instant it splits into two equal masses .The first mass move in a circular orbit of radius R/2 and the other mass in a circular A body of mass m moving in a circular irbit of radius R about a planet of mass M. At some instant it splits into two equal masses the first mass moves in a cicular orbit of radius R/2 and.. in a circular orbit of radius R about a planet of mass M. At some instant, it splits into two equal masses. The first mass moves in a circular orbit of radius (R/2), and the other mass ...The energy required to move a satellite of mass m from an orbit of radius 2R to 3R around earth of mass M is a). 12. GMm. R b). GMm. R.

Answer 2

Answer

Explanation:

Initial energy = PE + KE

= − GMm/R + 1/2GMm/R

​ = − GMm/2R

​

Final energy = −GMm/2R − −GMm/6R

​

ΔE= −GMm/6R
