Question
In a centrifuge rotating at ω rad/s, a particle at radius r from the axis experiences a centrifugal pseudo force (in rotating frame) of:
- Amω²r outwardCorrect
- Bmω²r inward
- Cmωr outward
- Dmg outward
Correct answer
mω²r outward
Explanation
In the rotating frame, the centrifugal pseudo force = mω²r directed radially outward.
