The figure below shows a spherical shell of mass `M` -and radius `R` in a force-free region with an opening. A par'ticle of mass `m` is released from a distance `R` in front of the opening. If the speed with which the particle will hit the point `C` on the shell, opposite to the opening, is `v=sqrt((n G M)/(4 R))`, Find `n`
