Actually, the new gravity would be 4 * the ratio of radii. If it's the same size of Earth but denser, it'd have more gravity. If it's radius is 4 times that of Earth (ie, same density as Earth, just bigger), the radius and mass should cancel each other out to have a force of gravity roughly 10 m/s.

Edit: Got the numbers.
http://en.wikipedia.org/wiki/Gliese_581_g

3.1 – 4.3 Earth Masses
1.3 – 2 Earth Radii

So it should have double the gravity, roughly.

Edit2: I read the wiki
Surface gravity (g) 1.1 – 1.7[1] g
