A solid sphere $\displaystyle (A)$ of mass $\displaystyle 5 m$ and a spherical shell $\displaystyle (B)$ of mass $\displaystyle m$, both having same radius, are placed on a rough surface. When a force of same magnitude is applied tangentially at the highest points of $\displaystyle A$ and $\displaystyle B$, they start rolling without slipping with an acceleration of $\displaystyle a_A$ and $\displaystyle a_B$, respectively. The ratio of $\displaystyle a_A$ and $\displaystyle a_B$ is $\displaystyle \_\_\_\_$.
