Calculating Centrifugal & Coriolis Forces at Rest

[tina21]

Homework Statement

Calculate the values of the centrifugal and the Coriolis forces in a mass of 20g placed at a distance of 10cm from the axis of a rotating frame of reference, if the angular speed of rotation is 10 radians per second.

Relevant Equations

n/a

so I can find the centrifugal force but shouldn't the Coriolis force be 0 because the mass is at rest?

At rest as viewed in which frame?
