q8 Carla and Jenny are arguing about whether or not it is possible to escape the gravitational field of the Earth. Carla shows Jenny asystem where mass m is rE (not the Earth's radius) distant from Earth and r p (not planet P's radius) distant from planet P. the massbeing on the line connecting the Earth and planet P. Carla states that the mass m has escaped if F P on m = -FE on m- Jenny disagrees.Which one, if either, is correct, and why?A Carla, because the total gravitational force on m is zero at that point.B Carla, because there is no gravitational force from Earth on m at that point.Carla, because there is no gravitational force on m from Earth when r> rE.(D Jenny, because there is a gravitational force on m from Earth no matter how great the distance from the Earth.(E Jenny, because the gravitational force from the Earth can only be blocked by a body that is larger than the Earth.

and Jenny are arguing about whether or not it is possible to escape the gravitational field of the Earth. Carla shows Jenny a m where mass m is rE (not the Earth's radius) distant from Earth and r p (not planet P's radius) distant from planet P, the mass g on the line connecting the Earth and planet P. Carla states that the mass m has escaped if F p on m = -FE on m: Jenny disagrees. h one, if either, is correct, and why? Carla, because the total gravitational force on m is zero at that point.
