It would make the gravity of the star have more power.
As for your question, it all depends.
If the planet was bigger than the star, the star would be pulled in gravatationally(if that's even a word).
If the star were bigger than the planet, the planet would be pulled in.
If there is more mass, there will be more gravitational attraction.
Yes. At a greater distance, the gravitational attraction between two objects is less.
On Earth it's the moon.
Gravity is proportional to mass and inversely proportional to the square of the distance between the two bodies.
Newton's equation of gravity is F=G(M1M2)/R2 where F is the force (gravity), G is the gravitational constant, which is about 6.67*10-11 N-m²/kg². However, this is not part of the problem. The M's are the masses of the objects and R is the distance between the two bodies. If the star's mass (M1) were doubled, then the attraction between the star and the planet would also double.
The reduction in the force of attraction between the nucleus and outer most electron is known as shielding effect
This is false. The answer is that mass and distance affect the gravitational attraction between objects. Air resistance has no effect on this.
electronegativity
It is not the gravitional effect ON the moon, but the gravitional effect OF the moon. The moon pulls on the earth, just as the earth pulls on the moon. The pull of the moon causes water to be drawn towards the moon, and forms a "bump" in the level of water. As the earth rotates below the water, the raised part of the water has the effect of making the water get deeper, then shallower. Those are the tides.
the gravitational attraction would increase, because the more mass something has the more gravitational pull it has.
Forces of attraction have a stronger effect on the behavior of liquid particles.
Double the mass means double the attraction in this case.Double the mass means double the attraction in this case.Double the mass means double the attraction in this case.Double the mass means double the attraction in this case.
