Question

80. Three particles of equal masses are placed
at the corners of an equilateral triangle, as
shown in fig. Now particle A starts with a
velocity v, towards line AB, particle B starts
with a velocity v, towards line BC and
particle C starts with velocity v, towards
line CA. The displacement of C.M. of three
particle A, B and C after time "t" will be
(given if v1 = V2 = v3)​.​
