Solution

The correct option is B $\to v = \to r \times \to ω$
Here $\to v = \to r \times \to ω$ is the wrong equation. As $\to v = \to ω \times \to r$ here direction of $\to ω$ is found out using right hand screw rule , where curled finger will show the direction of rotation and outstreched thumb is in the direction of $\to ω$ .
