An object A of mass .m. is located at a point .P. at distance .r. and .2r. from two planets B and C of masses .M. and .6M. respectively as shown in the figure. If theescape of the object A form point .P. due to the gravitational infulence of only planet B is 5ksm^(-1) , then the escape speed of the object A from point .P. due to the gravitational influence of both the planets is ......... kms^(-1) .
