If a planet of given density were made larger its force of attraction for an object on its surface would increase because of planet’s greater mass but would decease because of the greater distance from the object to the centre of the planet. Which effect predominate?
a)
Increases in mass
b)
Increase in radius
c)
Both affect attraction equally
d)
None of the above

(a) Let
If size of the planet is made double
New force

be the original radius of a planet. Then attraction on a body of mass 
placed on its surface will be
then mass of the planet becomes
force of attraction increases due to the increase in mass of the planet
