Answer :

If the earth were twice as massive as it is now, the gravitational force between it and the sun would be twice as massive as it is now

Gravitational force of 2 objects can be determined as below:

F = G [tex]\frac{m_{1}m_{2} }{r^{2}}[/tex]

With, F = Gravitational force

G = Gravitation constant

m1 = mass object 1

m2 = mass object 2

r = distance between object

If earth mass became twice as massive as it is now, the gravitational force can be compared by using equation above :

F1/F2 = G [tex]\frac{m_{1}m_{2} }{r^{2}}[/tex] / G [tex]\frac{m_{1}m_{2} }{r^{2}}[/tex]

F1/F2 = m earth/ 2 m earth

F1/F2 = 1/2

F2 = 2F1

with,
F2 = gravitational force with earth mass became twice as massive as it is now

F1 = gravitational force with earth as it is now
