In a cyclone separator used for separation of solid particles from a dust laden gas, the separation factor is defined as the ratio of the centrifugal force to the gravitational force acting on the particle. $S_{r}$ denotes the separation factor at a location (near the wall) that is at a radial distance $r$ from the centre of the cyclone. Which one of the following statements is $INCORRECT$?

1. $S_{r}$ depends on mass of the particle
2. $S_{r}$ depends on the acceleration due to gravity
3. $S_{r}$ depends on tangential velocity of the particle
4. $S_{r}$ depends on the radial location $(r)$ of the particle
