as the mass of jupiter is more than the mass of earth it has a greater graviationsl force in it........as we know that our weight depends on mass of object and thr gravitational force on it......if the gravitational force is increased the object's weight will definitely increase......
Due to more mass of jupiter than earth it means that there are more forces acting on every single point where mass acts......if these points are more the gravitational force will also increase.......
HOOE IT HELPED !!!!
