The escape velocities of two planets $A$ and $B$ are in the ratio $1 : 2$. If the ratio of their radii respectively is $1 : 3$, then the ratio of acceleration due to gravity of planet $A$ to the acceleration of gravity of planet $B$ will be:\\
(1) $\frac { 4 } { 3 }$\\
(2) $\frac { 3 } { 2 }$\\
(3) $\frac { 2 } { 3 }$\\
(4) $\frac { 3 } { 4 }$
