Question

Match List I with List II:

List I	List II
(A) The linear momentum of the system remains constant	(IV) The net external force acting on a system of particles is zero
(B) The angular momentum of the system remains constant	(III) The external torque acting on a system of particles is zero
(C) Inertial frame	(I) The frames relative to which an unaccelerated body appears unaccelerated
(D) Non-inertial frame	(II) The frames relative to which an unaccelerated body appears accelerated

Choose the correct answer from the options given below:

• A. A-III, B-IV, C-I, D-II
• B. A-IV, B-III, C-I, D-II
• C. A-IV, B-III, C-II, D-I
• D. A-III, B-I, C-IV, D-II

Hint:

An inertial frame is one with no net acceleration; a non-inertial frame is accelerating, leading to fictitious forces.

Answer 1

The Correct Option is B

A. Linear momentum const. → Net external force = 0 (IV),
B. Angular momentum const. → External torque = 0 (III),
C. Inertial frame → Unaccelerated body appears unaccelerated (I),
D. Non-inertial frame → Unaccelerated body appears accelerated (II).
