An object A of mass ‘m’ is located at a point 'P' at distances ‘r’ and '2 r’ front two planets B and C of masses ‘M’ and ‘6M’ respectively as shown in the figure. If the escape speed of the object A front point 'P‘ due to the gravitational influence of only planet B is 5 kms−1, then the escape speed of the object A from point ‘P’ due to the gravitational influence of both the planets is______________kms−1.
