INERTIAL MASS

NON-INERTIAL FRAME OF REFERENCE

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.

Statement-I : Time period of spring block system is the same whether in an accelerated or in an inertial frame of reference. Statement-II : Mass of the block of spring block system and spring constant of the spring are independent of the acceleration of the frame of reference.

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

Equivalence Of Inertial And Gravitational Masses

A simple pendulum has a length I. The inertial and gravitational masses of the bob are m_(i) and m_(g) , respectively. Then, the time period T is given by

Compare the magnitude of moment of inertis of masses and radius are equal (a) Ring about Diameter (I_a) (b) Disc about perpendicular axis passing through centre (I_b) (c) Solid cylinder about axis (I_c) (d) Solid sphere about axis passing through centre (I_d)

Two frame S_(1) and S_(2) are non-inertial. Then frame S_(2) when observed from S_(1) is inertial. A frame in motion is not necessarily a non-inertial frame

STATEMENT-1 : The relation vectau=(dvecL)/(dt) is applicable in centre of mass frame, even though the centre of mass is accelerating. and STATEMENT-2 : The relation vectau=(dvecL)/(dt) can be directly applied in a non-inertial frame.

These questions consists of two statements each printed as Assertion and Reason. While answering these question you are required to choose any one of the following four responses Assertion Earth is an inertial frame. Reason A frame in motion is sometimes an inertial frame and sometimes a non-inertial.
