Planet X, because the sun pulls it with a greater force

Explanation:

It is given that  planets X and W have same mass but are at difference distances from the Sun.

Planet X is closer to Sun than planet W.

As the gravitational force is inversely proportional to the square of the distance, the gravitational force between the Sun and planet X would be greater than between sun and planet W.

From Kepler's law of planetary motion, we understand that closer the planet, greater would be its speed of revolution around the star. As the line joining the star and the planet must sweep equal areas in equal intervals of time. Thus, planet X would revolve at a faster speed.
