Hi there!

We can use the following equation to solve for gravitational acceleration for a uniform mass:

g = (Gm)/(r^2)

g = acceleration due to gravity (m/s²)

G = Gravitational Constant

m = mass of PLANET (kg)

r = radius (m)

Plug in the given values:

g = ((6.67*10^(-11))(6 * 10^(24)))/((3.9*10^6)^2) = \boxed{26.31 (m)/(s^2)}
