If a planet of given density were made larger its force of attraction for an object on its surface would increase because of planets greater mass but would decrease because of the greater distance from the object to the centre of the planet. Which effect predominates?

both effects are predominant because according to newtons low of gravitation the force of attraction between two masses is directly proportional to product of these masses and inversely proportional to square of distance between them . as planet has greater mass the force will increase . And the force will decrease because the distance between object and planet will increase .

Increase in mass
Explanation:
I am not sure but I feel increase in mass as force F is directly promotional to 2 masses but it is inversely proportional to R^2 please let me know if I am wrong
