Does Centripetal force cause a tangential force?

If I have a string with a lump on the end and is being swung in a circle with a continuous angular velocity then I know that:
[tex] F= m\frac{v^2}{r}[/tex] or using angular velocity, [tex] F= m r \omega^2 [/tex] But, is there a tangential force acting at the point of mass in its instantaneous direction, and if so, what is it equal to?

Hi Kalus!
("/tex" not "\tex" ) There's a tangential force only if there's a tangential acceleration (Newton's second law). If the angular speed is constant, there isn't.
