For the uniform rod with marked points A, B, C and D, match Column-I with Column-II.

Column-I

Column-II

(A) Moment of inertia maximum about axis through

(P) Point A

(B) Moment of inertia least when hinged about

(Q) Point B

(C) Elastic collision gives maximum rod angular speed when struck at

(R) Point C

(D) Elastic collision gives maximum rod centre speed when struck at

(S) Point D

 

(T) Points A and D

Answer:
A-P; B-R; C-T; D-R
Solution:

For moment of inertia, compare the squared distance of each rod element from the chosen axis.

For the collision cases, apply conservation of angular momentum about the impact point.

The required matches are A → P; B → R; C → T; D → R.
