c)Ans (t)
Let velocity of B be x(tangential)
its comp. along length of rod=vcos60
Comp of vel. of A along length of rod=3cos60

Now as rod cannot contract along its length:
v=3

d) should be (t) [v2/r]

a)Ans:(p)
vel of B is opp. that if A.
The comp. of both particles perpendicular to rod=vsin60=3*√3/2
w=v/r=3*√3/2/(3/2)=√3

Hmm.. I too do the same way. But I'm never sure of it. What do I do? :(
