Equivalence Of Inertial And Gravitational Masses

Assertion: The ratio of intertial mass to gravitational mass is equal to one. Reason: The inertial mass and gravitational mass of a body are equivalent.

Assertion: Linear momentum of a planet does not remain conserved. Reason: Gravitational force acts on it.

Assertion : A body falling freely may do so with constant velocity. Reason : The body falls freely, when acceleration of a body is equal to acceleration due to gravity.

Assertion : An astronaut in an orbiting space station above the earth experience weightlessness. Reason : An object moving around the earth under the infuence of earth's gravitational force is in a state of 'free fall'

A cabin is falling freely under gravity, what is the time period of a pendulum attached to its celling?

Assertion : If a pendulum falls freely, then its time period becomes infinite. Reason : Free falling body has acceleration, equal to 'g'.
