Three equal masses 
are kept at vertices (A, B, C) of an equilateral triangle of side a in free space. At 
, they are given an initial velocity 
and 
. Here, 
and 
are unit vectors along the edges of the triangle. If the three masses interact gravitationally, then the magnitude of the net angular momentum of the system at the point of collision is :
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
