A particle of mass $\displaystyle m$ is moving around the origin with a constant force $\displaystyle F$ pulling it towards the origin. If Bohr model is used to describe its motion, the radius $\displaystyle r$ of the $\displaystyle n^{\text {th }}$ orbit and the particle's speed $\displaystyle v$ in the orbit depend on $\displaystyle n$ as
