PHXI07:SYSTEMS OF PARTICLES AND ROTATIONAL MOTION

365788 Assertion :
The centre of gravity of a body coincides with its centre of mass only if the gravitational field does not vary from one part of the body to the other.
Reason :
Centre of gravity is independent of the gravitational field.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
PHXI07:SYSTEMS OF PARTICLES AND ROTATIONAL MOTION

365789 Statement A :
The centre of mass of a body may lie where there is no mass.
Statement B :
The centre of mass has nothing to do with the mass.

1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.

PHXI07:SYSTEMS OF PARTICLES AND ROTATIONAL MOTION

365790 Assertion :
The centre of mass of a proton and an electron remains at rest if they are initially at rest relative to each other.
Reason :
The centre of mass remain at rest, if no external force is applied on the system.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
