Momentum and CollisionHard
Question
Two particle A and B start moving due to their mutual interaction only. If at any time ′t′ 
and 
are their respective accelerations, 
and 
are their respective velocity and up to that time WA and WB are work done A and B respectively by the natural force, mA and mB are their masses respectively then which of the following is always. correct.
and are their respective accelerations, and are their respective velocity and up to that time WA and WB are work done A and B respectively by the natural force, mA and mB are their masses respectively then which of the following is always. correct.Options
A.+ = 0
+ = 0B.mA+ mB= 0
+ mB= 0C.WA + WB = 0
D.
+ 
= 0
+ = 0Solution
absence of external forces, the linear momentum of the system remains constant.
