The no.of correct statements are 1) The apparent weight of a freely falling body is zero II) Applied force is a example of pseudo force III) Pseudo forces exist for observers only in non inertial frames, such forces have no existence relative to an inertial frame

Inertial and Non Inertial Frame||Pseudo Force

Statement I: A concept of pseudo force is valid both for inertial as well as non-inertial frame of reference. Statement II: A frame accelerated with respect to an inertial frame is a non-inertial frame.

Consider the following two statements A and B and identify the correct choice in the given choices (A) Centripetal force, centrifugal force are equal in magnitude and opposite in direction but they are not force of action and force of reaction respectively because both act on same body. (B) Centrifugal force is a pseudo force in both inertial frame of reference and non inertial frame of reference.

What are non-inertia frames of refernce? Give examples. What are frictitious or pseudo forces?

The acceleration of a particle is zero as measured from an inertial frame of referecne. Can we conclude that no force acts on the particle?

If the Newton's laws of motion are to hold true in an accelerated frame of reference then the observer in this frame of reference will assume the existence of pseudo force known as

Problems of non-intertial frames can be solved only with the concept of pseudo force. Is this statement true or false?

A body is rotating uniformly about a vertical axis fixed in an inertial frame. The resultant force on a particle of the body not on axis is

If the resultant of all the external forces acting on a system of particles is zero, then from an inertial frame, one can surely say that
