Yup, the answer would be the same.
G (m)/r^2
Use the inverse square law. Two times the radius squared is 4r, so put this in the denominator. For the numerator, take 4m and divide it by 4r. This gives you the original equation, so its new value is the same.

The same! 2 times the distance means 1/4 the gravity and 4 times the mass means 4 times the gravity. 1/4 * 4 = 1

the same
gravitational field (g) depends directly on mass of the body and inversely on the distance square.
g = G M / r^2
where G is the universal gravitaional constant. So if i inc mass 4 tims and and diameter is twiced ( is radius is also twiced ) g remains the same!
