- Which is real?
- Which frame?
- JEE preference?
Notes: Centripetal force is a real force (or the net radial component of real forces) directed toward the centre. It is not a separate force — it is provided by tension, gravity, normal force, friction, or their combination.
Centrifugal force is a pseudo (fictitious) force that appears only in the rotating (non-inertial) reference frame. It equals m**r directed outward. It is NOT real.
JEE approach: Always work in the inertial (ground) frame. Set the net radial component of all real forces equal to /r. Never add centrifugal force in the inertial frame.
Summary: In the ground frame, there is no outward force. The body would fly off tangentially (not radially outward) if the centripetal force were removed.
