If a body moves in a circular path of radius \( r \) at angular speed \( \omega \), which expression gives its linear speed?

1. If a body moves in a circular path of radius \( r \) at angular speed \( \omega \), which expression gives its linear speed?

1. \( v = r\omega \)2. \( v = \omega/r \)3. \( v = r/\omega \)4. \( v = \omega^2r \)
