Two spherical stars A and B have densities rohA and rohB, A and B have the same radius, and their masses M(A) and M(B) are related by M(B)=2M(A). Due to an interaction process, star A loses some of its mass, so that its radius is halved, while its spherical shape is maintained, and its density remains rohA. The entire mass lost by A is deposited as a thick spherical shell on B with the density of the shell being rohA. If v(A) and v(B) are the escape velocity form A and B after the interaction process the ratio v(B)/v(A)=SQRT[(10n)/(15)^(1/3)]. The value of n=?
