Centrifugal force in a rotating frame is best described as a
Apseudo force
Breal contact force
Cgravitational force
Dmagnetic force
Answer & Solution
Correct answer: A. pseudo force
1. Centrifugal force appears only when motion is analysed in a rotating (non-inertial) frame.
2. It has no real source (no field or contact agent producing it).
3. It is therefore classified as a pseudo or inertial force, equal in magnitude and opposite in direction to centripetal force in that frame.
