Q. Assertion :We can calculate angular momentum of bodies of all shapes by the product of moment of inertia and angular velocity Reason: The basic equation of torque i.e.,torque is equal to rate of change of angular momentum is valid for both inertial and non inertial frames.

Q. Assertion :If no external force acts on a system of particles, then the centre of mass will not move in any direction. Reason: If net external force is zero, then the linear momentum of the system changes.

Q. A block moving in air, explodes into two parts. Then just after explosion (neglect change in momentum due to gravity)

Statement

1

:- The total momentum of the two parts must be equal to the momentum of the block before explosion.

Statement

2

:- If no external force acts on a system, then the linear momentum of the system will be conserved.

Q. The formula that torque equals the rate of change of angular momentum is true in following general cases:
