Two particles A and B of mass m each, are joined by a rigid massless rod of length λ . A particle P of mass m, moving with speed u normal to AB, strikes A and stick to it. The centre of mass of the 'A + B + P' system after collision is C. If u = 4m/s, m = 3 kg, λ = 3 m, then (All quantities in column are in SI units)
Column I | Column II |
(i) AC is equal to | [A] 12 |
(ii) Angular momentum of system about C is | [B] |
(iii) Moment of inertia of system about C is | [C] 18 |
(iv) Angular velocity of system about C is | [D] 1 |

Ans.
(i) [D]
(ii) [A]
(iii) [A]
(iv) [B]
Sol. AC = 
Angular momentum about C = mu 
moment of inertia about C
= 2m 
+ 
Angular velocity =
