Two particles A and B start moving due to their mutual interaction only. If at any time 't', 
& 
are their respective accelerations, 
and 
are their respective velocities, and upto that time w A and w B are the work done on A & B respectively by the mutual force, m A and m B are their masses respectively, then which of the following is always correct.
A
+ 
= 0
B
m A 
+ 
m B = 0
+ m B = 0
C
w A + w B = 0
D
+ 
= 0
Text Solution
Verified by ExpertsThe correct answer is:
B
Since Σ 
= 
∴ Moment of system will remain conserved, equal to zero.
