JEE — Centripetal vs CentrifugalMediumQuestion 30667

Question

In the inertial (ground) frame, there is:
  1. A
    Centrifugal force
  2. B
    Centripetal force (real force)
    Correct
  3. C
    Both centrifugal and centripetal forces
  4. D
    Neither; circular motion has no special force

Correct answer

Centripetal force (real force)

Explanation

In the inertial frame, the real radially inward force (gravity, tension, friction, etc.) is called centripetal. Centrifugal force is a pseudo force that exists only in the rotating (non-inertial) frame.
